Information about VoIP (Voice over IP) - Quality of Voip Phone Service - IP Phone Service

As the networks originally designed for data, VoIP adoption also is needed to ensure that our voice has priority, that because the conversations occur in real time, so it is unacceptable that VoIP packets arrive late or too late or never. To resolve this problem we have created mechanisms to ensure that VoIP packets are prioritized over a network, so-called quality of service (QoS).

The factors involved in the voice quality is as follows:

• Codec
• Bandwidth Latency
• (Redardo the arrival of packets)
• Jitter (latency variation)
• Loss Package

It is common that people think that just by increasing the bandwidth to VoIP is to solve your problems, but this is not necessarily true.

Suppose your company is in common use IP phones that integrate two Ethernet ports, so you share a single point in the IP network between your phone and your computer. However, suppose that you need to frequently transfer files between your PC and other network equipment, as well as the transfer is an 'avalanche' of information that tends to consume all available bandwidth on your connection to the network which seriously affects the application performance audio or video.

Most applications have a low priority on the network and tend to be tolerant of delays, for example slight delay while you get the news will not affect your goal of seeing the news, but it would be unacceptable in its communication by VoIP if teleñfonica these affect the voice quality and generating difficulty understanding what you say or what you say.

The ability to allow the packet loss in IP telephony is very low and should be kept below 2% that does not affect the quality markedly. But the problems that actually affect IP telephony are latency, jitter and boring ECO.

Latency

Is defined as the delay between sending and receiving packets, but from a user's point of view is defined as the gap in the conversation generated by the delays accumulated during the transfer delays and packet processing. The latter delays are often overlooked but it should be noted that while the G.711 codec produces a negligible processing delay of the G.729 tends to produce a larger delay due to compression process performed on the voice.

Delays due to compression can be reduced when using the codec G.711 instead of G.729 whenever possible, for example in local area networks where bandwidth is not a constraint, but connections using the Internet is still requires a compressor to reduce the bandwidth used by each call.

Delays due to the network can be measured with various tools (Cacti, Ethereal, etc) and usually can be adjusted to give attention to the physical components of the network that is often overlooked, such as connectors in poor condition, electric fields magnetic or too close (fluorescent lamps that intersect with the data cable), and others.

Jitter

Jitter is the variation in delays in the arrival of packets between the source and destination usually caused by traffic congestion at some point in the network or the difference in transit time of packets when they travel through different routes.

The usual solution is to use a Buffer (Jitter Buffer) to store the packages before delivery to the destination to ensure they all reach the destination in order, although this introduces an additional delay. In applications such as IP Telephony Asterisk can be configured for a jitterbuffer correct this problem.

On the other hand when it comes to Jitter in LAN or WAN are usually corrected by increasing the bandwidth, of course prioritizing packets will always be an alternative.

Eco

When we have latency and jitter in a VoIP communication can produce the phenomenon of Eco what is usually resolved using 'echo canceller', whether software or hardware.

There are 2 common types of echo: a high level and low-delay that is produced locally and a low level and further delay that occurs in the remote end. Both can be removed by the echo canceller, but it is important to understand that usually echo canceller hardware is more efficient than those built by software, that rule applies mainly to applications such as IP Telephony Asterisk Software although recently have been released by Echo Canceller Octasic software (not GPL), which have proved highly effective in the treatment of the echo.

On the other hand sometimes the echo is within the same IP phone by poor acoustic design or by direct influence of the materials that have been built, which can affect the performance of low-cost IP phones that have an even electronics quality sound level are affected by allowing a return of the voice between the headset and microphone. Usually this type of echo can not be solved with external echo canceller to the phone.

Packet Loss

The percentage of packets that do not reach their destination measures the loss of network packets. This loss may occur because of errors in any of the computers that allow the network connectivity or exceed the capacity of a buffer of a computer or application in times of congestion. Typically in applications that do not work in real time can take advantage of the retransmission of packets, but IP telephony operating in real time and packages can not be broadcast.

Classification & Prioritization

QoS Quality of Service is responsible for providing a level of service for different applications using the network can benefit from it in an appropriate manner, and since not all applications have the same standards of network quality service is assigned to each requirement that requires.

To talk about quality of service we must classify the traffic that travels through our network. Some applications may then be identified by the port they use to move their packages while others can use dynamic ports such identification impossible.

The most common ways to classify traffic on a network are:

• Protocol
• Port Number
• IP Header
• RTP header
• Content (eg, URL)
• Velocity and Flow Pattern
• RSVP Signaling
• Tags routing
• Signatures custom applications

Normally, the classification review, the contents of the package such as the IP protocol, port number or destination, this classification can be performed anywhere on the network, either at ends or in the middle of the network.

Today switches are common to prioritize network packets at the extremes and are an appropriate way to ensure that our packages arrive at their destination in the desired conditions, it is also possible to prioritize packets through traffic management equipment, bandwidth or through firewalls.

The routers can prioritize packets in a network environment and is quite common today, but there are usually less aware of traffic at both ends so that the routers are generally classified by size of package, flow velocity, but can also do it for content and direction.

Not usually reliable ranking delegate to end users or the same application and provided better results, leaving the classification system to one that specializes in such work, although the trend is that both SoftPhones as IP gateways play a role important in the QoS of the VoIP network.

Yahoo Messenger with Voice - VoIP International Calls

Yahoo Messenger is the category of instant messengers (IM) programs that allow you to have an account and use it to contact you more contacts, send files and photos, and also do video conferencing with a webcam and a microphone.

Respect for Skype has more functionality, but currently does not allow you to call phone numbers then you can only call other people who have a Yahoo account. The advantage is that everything's free, and if you want to share files (photos) to your beloved, it is easier to send via email.

Also if you have a Yahoo mail, you can integrate into the program so that tells you when it is switched on at the time when e-mails arrive. You can also play with friends, going into public chat (text, voice or video), read the news and things of this style. It is like saying, a multimedia center.

VozTelecom Voip Service - IP Telephony Service

What is IP telephony?

Internet telephony or IP telephony is that telephone service is based on VoIP technology. IP telephony is an immediate application of this technology, so as to enable the realization of ordinary telephone calls over IP networks or other packet networks using a PC, gateways and standard telephones or IP phones.

The basic steps that take place in a call via the Internet are: converting the analog voice signal to digital format and compressing the signal to an Internet protocol (IP) for transmission. At the reception is the reverse process to recover back the analog voice signal.

Over many years, the VoIP telephony market is in both individuals and businesses, but it was not until recently that its use is widespread due to better penetration and lower cost of broadband and the improvement of technologies to ensure service availability and quality of IP calls equivalent to traditional telephony.

Voice and data convergence with IP Telephony VoIP or Telephony

We speak often nowadays of converged networks, referring to a concept of integration on the same network for all voice communications, data, and video, etc. The convergence between voice and data IP telephony enables the creation of applications with high added value for the company to multiply the uses and benefits now offered by the conventional telephone network.
Benefits of IP telephony or Voice IP Telephony for business

The benefits of VoIP telephony as the common denominator is the reduction in the cost of communications. IP telephony permits reduction of call costs or infrastructure costs. Moreover, it allows growth without obsolescence of its equipment, productivity improvements and new features to bring added value to the company and the workers.

IP Phone Service - VOIP Telephone Service

Internet Phone service is the telephone service as a basic technology of VoIP (voice over Internet protocol), which enables the conversion of voice into data packets to be transmitted over a data network as private or public Internet.

The convergence between telephony and IT (ICT) allows the creation of value-added applications that multiplied the uses and benefits now offered by the conventional telephone network (analog)

Voice over IP

Voice over Internet Protocol, also called Voice over IP, VoIP, VoIP (by its initials in English) or IP Telephony, is a group of resources that enable the voice signal to travel over the Internet using an IP protocol ( Internet Protocol). This means that sends the voice signal into digital form in packets rather than sending in the form of a circuit as a conventional telephone or PSTN ..

The protocols that are used to carry voice signals over the IP network are commonly referred to as Voice over IP protocols and IP protocols. Can be viewed as commercial implementations of the experimental Network Voice Protocol (1973), invented by ARPANET.

The Voice over IP traffic can travel on any IP network, including those connected to the Internet, such as local area networks (LAN).

Advantages

The main advantage of such services is that it avoids the high telephone charges (mostly long distance) that are customary for companies in the PSTN (PSTN)). Some cost savings are due to using a single network to carry voice and data, especially when users have not used the full capacity of an existing network in which they can use VoIP without additional cost. VoIP calls from any VoIP provider are generally free, in contrast to the VoIP to PSTN calls generally costs the VoIP user.

There are two types of PSTN to VoIP services: Direct Local Calls (Direct Inward Dialing: DID) and access numbers. Those who DID connect the call directly to the VoIP user while access numbers require that enter the extension number of the VoIP user. Access numbers are usually charged as a local call for those who made the call from the PSTN and free to the VoIP user.

Functionality

VoIP can facilitate tasks that would be more difficult to perform using the common telephone networks:

• The telephone calls can be automatically routed to your VoIP phone, regardless of where you're connected to the network. Take your VoIP phone on a trip, and wherever you are online, you can receive calls.
• Toll-free number for use with VoIP are available in the United States of America, United Kingdom and other countries from organizations such as VoIP User.
• Call center agents using VoIP phones can work anywhere with an Internet connection is fast enough.
• Some packages include VoIP services for which extra PSTN (Switched Telephone Network) normally charge an extra charge, or that are not available in some countries, such as 3 calls at once, return call, automatic redialing or Caller ID.

Mobile

The users of VoIP can travel anywhere in the world and still make and receive calls as follows:
The subscribers of telephone services can make and receive calls outside their local area. For example, if a user has a phone number in the city of New York and traveling through Europe and someone calls your phone number, this will be received in Europe. Also, if a call is made from Europe to New York, will be charged as local call, of course you travel to Europe must have an Internet connection available.
Users of instant messaging-based VoIP services can also travel anywhere in the world and make and receive phone calls.

• VoIP phones can integrate with other services available on the Internet, including video, data and exchange messages with other services in parallel with the conversation, audio conference, address book management and information exchange with others (friends, colleagues, etc. ).

With IP Telephony (digital) are available the following digital services:

1 .- Answering Machine (Voice e-mail)
2 .- Intelligent Call Forwarding
3 .- Block outgoing calls
4 .- The filtering of incoming calls
5 .- Conference up to 5 participants
6 .- abbreviated dialing (short numbers) virtual extensions,
7 .- Detail of calls and billing on-line (real time)
8 .- Incoming Caller ID
9 .- Call waiting
10.-Transfer of current call

IP telephony (digital) not only provides a better phone service also offers rates much cheaper than conventional telephony (analog).

The phone number that is assigned to the client is forever. This means that when moving from home, took her number.

Markets, services and agents

Forecasts vary widely in terms of economic opportunity that creates the market for IP telephony. According to TeleGeography, 2000 during the IP-based networks carried a volume of international traffic of about 3,700 million minutes, just over 3% of world trade but the market is growing rapidly. Market analysts predict that IP telephony in 2004 account for 25 (Analysis) and 40% (tariffs) of the total international traffic in the world. Most studies show that currently the main use of IP telephony is for international traffic and not for local traffic or domestic long distance. Today United States is the main source of traffic for IP telephony. TeleGeography estimates that 20 major routes IP telephony throughout the world by volume of traffic is established between United States and other countries (although some of this could simply be switched traffic through that country.) In the long term, IP telephony has a market opportunity in regard to local and long distance, especially if it slows the transition of prices to costs.

The market for IP telephony, as well as their products and their agents, is considerably different from traditional PSTN telephony market which, even today, is under the domination of the established operators. While most providers of IP telephony services (IPTSP) are owned by United States, its activities are primarily global in nature and not national, and often work in partnership with the PTO established, and provide training and technical competence as well as opportunities for generate income. The market segments can be in several different types of applications, namely (in the approximate order in which they appeared): PC to PC, PC to phone, phone to phone and value added services.

The market also segmented between wholesale and retail operations, or that offer services between IPTSP fixed price, and those offering free applications for end users, funded by revenue from advertising. It is also advisable to make a distinction between the way in which IP is used to carry voice signals, eg in networks of existing operators migrating to IP in the networks in the most recent PTO without direct connection with customers in the managed IP-based networks offering multimedia services, or through Internet service providers that interconnect the public Internet with the PSTN. The mainstay of the business, at least for now, is the arbitration of the price, but this is changing with time, as value added services ¾ such as integrated messaging, presence management ( "localíceme, follow me") and the "press to talk" of websites ¾ generate a revenue increase.
Costs and prices

Currently, consumers generally have to choose between price and quality. Willing to accept that commitment generally depends on the prices. Customers in countries with low income or low income families in developed countries, more likely than other consumers less concerned about price, choose the IP telephony, when they can. Residential customers may have more tendency to use IP telephony to business users for whom the quality of transmission and reliability are more important.

The precise nature of the cost advantages that IP networks offer the PTO is the subject of many debates. Depend, for example, the following:

• If a particular investment is a new IP network, or an improvement or an overlay to existing network. The incentive to choose the IP network will be larger for new or substantially new. For example, in Senegal, where the networks serve only 1% of the population, SONATEL planned to spend their existing core network to an IP basis in 2004 and offering voice services and data on the same IP network.

• If a company is the owner or a new entrant in the market. New entrants who have no need to defend a network, will probably be the first to be targeted to IP telephony. In China, for example, China Netcom to build a Voice over IP network to serve 15 cities and will be approximately 9600 km of fiber optic cable in late 2000. In the case of Hungary, which pushed the start to offer VoIP service providers were mobile they saw the possibility of circumventing the monopoly Matav to study international calls, despite the fact that the operator Matav is currently a IPTSP.

• To what extent are offered value-added services. In economies such as the Special Administrative Region (SAR) of Hong Kong and Singapore, where local calls are free (together with access rates), the new market offer value added services that allow, for example, that users can retrieve their voice mail (T2mail.com), providing voice mail and fax communications (2Bsure.com) by an IP platform.

Countries where the prices are high in international traffic

The main interest of IP telephony will be the price difference with respect to simple voice transmission. In many of these countries, the outgoing IP telephony is prohibited. Therefore, it is equivalent to IP telephony traffic. Although the use of IP telephony for inbound traffic is not much more if it is lawful for outbound traffic, it is harder to detect and block.

Countries in which prices decline in international traffic

Both retail (consumer) and the wholesale (liquidation), the IP telephony traffic and may be playing a role in the promotion of price competition (such as in Hungary or Thailand) or by offering an alternative to services from fixed line operator (eg in Colombia). However, one critical factor is the ease with which subscribers use the service. In Peru, for example, the success of IP telephony was based partly on the availability of a telephone-type device (Applied), which could be used in IP-based networks or the PSTN for communication (see case study in Peru page 21).

Countries where prices are already low international traffic

Due to the effects of competition, it is likely that IP telephony is important for other reasons that the price difference. It is likely that the business opportunity of IP telephony lies in the prospects of integrated value added services for users and cost reductions for the PTO. Example of the former is yac.com (United Kingdom), which offers a personalized service and numbers of retransmission automatic call via the Internet. Example of the latter is Concert, a joint venture between BT and AT & T, which is building a new managed global network to provide IP-based services such as electronic commerce and global call centers, to connect about 90 cities around the world . While the investment required is around 1,000 million USD annually, it is considered that an integrated IP network provides the most cost-effective solution to address multiple traffic flows.

VOICELINE IP Telephony - VoIP (Internet telephony)Service Vs Conventional Telephony

VOICELINE IP Telephony - VoIP (Internet telephony)Service Vs Conventional Telephony Service

How does VOIP works?

Originally the voice is digitized, compressed and encapsulated over TCP / IP (the one used on the internet). Destination is the operation.

Most economically advantageous

It is obvious that the supposed savings from the integration of two networks into a single (data). Maintenance, management and administration are lower because you can even centralize in one location. In such systems, 80% of problems can be solved remotely, compared to 45% is achieved in the traditional networks.

Moreover, the same way now that internal calls between the PBX extensions have no cost, with the VoIP solutions will also be free calls between all the delegations.

But not only that, with appropriate configuration can be achieved that calls for an outside area in which there is a delegation, quit it, and going to be kind of national or provincial, to be local.

Why is it cheaper to IP Telephony?

A telephone call requires a huge traditional telephone network (telephone dealing only), connected by fiber optic and satellite telecommunications. The huge investments needed to create and maintain the infrastructure that we have to pay when making calls, especially long distance calls. Furthermore, when a call we have a dedicated circuit with a bandwidth of 64 Kbits, we do not use 100%.

However, in an IP phone call we compress the voice signal and releasing bandwidth in the silences.

Being single infrastructure for voice and data traffic, maintenance (lower) is shared between the two. On the other hand, if we look globally for the whole network, we see that the similarity between infrastructure client / operator makes it less complex network operator, as it delivers traffic encapsulated in IP.

All this, together with the optimal use of bandwidth, makes the cost of calls to the operator is lower. Some operators have shifted part of this benefit to the customer.

Do I have to change my infrastructure?

No. With VoIP, no need to change their networks. You can undertake an expansion and implemented with IP technology, complemented perfectly with traditional systems. The functions FXO, FXS and Q-sig have been designed for that. That way you can build your entire infrastructure. In any outlet can put an IP Phone.

VoIP expanding your business. When you grow up, or because they prefer to share the investment in different times, you can always take advantage of the previous investment. You can enter the IP technology in an apartment and after seeing the advantages, continue to rest.

Any other advantages?

With IP technology transfers, distribution changes in their offices, they are cheaper. The phones are in service to connect to any outlet. Not changed the phonebook, the staff is located since they are online. The numbering is no longer linked to a site.

VOIP:- A world full of possibilities. Yet, these advantages are insignificant when compared with the possibilities offered by the LAN telephone to introduce new and exciting applications of advanced communications, such as:

• Unified messaging.
• Virtual call centers, Web-based.
• "Push 2 Talk" to offer customers the ability to contact you and the various departments of your company free of charge through its website, without having to cut the connection.

And, in general, all related to the integration of computing and telephony. Furthermore, it works regardless of the means of transport and access device, from phones to endure, to IP phones and mobile multimedia computers, laptops, Tablet PCs and PDAs.

What is the difference in VOIP and IP telephony?

VoIP stands for Voice over IP protocol (in English). It is the technology that digitizes, compresses and encapsulates the voice over IP protocol.

With the teams that respond to this technology, we can make internal calls to the corporate LAN, without any cost.

IP telephony is the infrastructure that allows us to make any phone calls to the telephone network. We therefore need a gateway to interconnect our network with an operator.

What type of terminals used for?

The terminals used are different from traditional analog phone (you can take) until the new terminal IP (much like the traditional look), via a multimedia PC with the right software (the cheapest option, when the PC is required for the job).

Do what type of terminals can make calls?

Among all types of terminals can make calls. All combinations are possible.

Can I send faxes?

Yes, this technology is capable of sending faxes via the IP protocol.

This option allows you to save the fax machine, using the right software, and more importantly, it opens the possibility of making a documentary file on computer, entering into the paperless office.

Does this technology only works with ADSL among delegations?

No. Any media is valid, our wireless networks, point to point circuits, ISDN, PSTN, etc.

The differences lie in the cost and bandwidth. Our wireless solutions cost is zero, once acquired, with a wide bandwidth (easily achieved 1, 2 and 5.5 Mbps and can reach even 11 Mbps in optimal conditions). In ADSL, the monthly cost is fixed. ISDN and PSTN, the cost depends on the connection time (if not flat rate) and bandwidth is very limited.

It is not an expense is an investment. The cost of implementing the system is not an expense, should be considered an investment. Computing and communications is not always easy to see the returns, but with VoIP solutions as you will see spending on your bill is dramatically reduced because very soon you start saving money.

Rapid Return on Investment.

Several factors contribute to the rapid depreciation of the system: number of delegations, current telephone lines, data network, the need for communication among the delegations.
Of these, undoubtedly the most important influence is the need for communication among the delegations.

Morrotel VoIP services - Internet Telephone Services

TELEPHONY - VOIP technology? savings on telephone and a further example, Morrotel, a new company with very competitive prices. All suffer the prices of mobile operators, which offer relatively low rates when you call your own but totally unfair when calling other companies.

Nobody on the money and there is no better option than trying to pay less phone, and one of these options is IP telephony.

Morrotel VoIP services

There are already offers on the market that work better or worse way, and here is a new company with prices extremely competitive.

But each will have their opinion on the matter so it is best to let us know.

In this case gives us Morrotel € 0.09 to call any mobile operators and fixed telephones to € 0.01.

Skype VoIP Telephone Service Vs Traditional Telephony

Skype enables VoIP communication with other Skype users. Is not a big deal today, for the incumbent. But it also allows you to communicate with any other phone out of the Internet, i:e also called as a Voip Telephone Service or Internet Phone Service with prices cheaper than a traditional telephone carrier. That is already beginning to be more worrisome.

What can the operators? Because the Internet is a cake that all want their slice. But offering internet access services, offering both the possibility for users to use Skype and stop using their phone service. Nor can they prevent the use of Skype (even if technically possible), because users will move to competition. Are, in short, in a difficult situation.

Another option? Offer VoIP services themselves, such as Iran doing in the coming months. However, that will reduce their income rates. And the cost? Let us not forget that the infrastructure of fixed telephony is still there. Will continue to be amortized as the major channel for the provision of internet access, but ... what will happen when the widespread use of mobile internet, via WIFI, WIMAX or whatever comes?

And the provision of universal service in telephony ... will take place on VoIP? Who bears the costs of updating the technology to people who have not done yourself?

Best IP Telephony Service - Best Voip Telephony Service - Best Internet Telephone Service

Today we speak of a new service for which they have bet on the same criteria of quality, IP telephony, their rates are much more competitive than those of such as Skype, in fact, Voip telephony orIP is gaining market to traditional the debate is always served as the site of dichotomies:

• VoIP or IP Telephony Vs. Conventional Phones
• VoIP Phone Services Vs Traditional Phone Services

Taking advantage of Internet calling is possible throughout the world with incredible rates, even cheaper to call your neighbor. Less than 2 cents per minute to Spain, Argentina, Germany, France, Denmark, United Kingdom, Greece, Italy, Poland, Portugal, United States, Canada, China, India, etc.. The trick is to take the Internet call to the closest point to the destination, thus making international calls national calls. There are several ways to take this revolution in telephony:

1.-IP Telephony Service

Besides being able to call from your PC throughout the world, and free between PCs, you can use an IP phone or adapter to your existing phone you do not have to have the PC switched on. It is also possible to associate your account with an IP telephony or more numbers in over 40 countries providing international numbers, and start calling or sending an SMS via web or WAP.

2.-Virtual Calling Cards

For those who do not want complications with programs or the Internet. Simply call any local access numbers in Spain, Argentina, Mexico or Brazil.

3.-Numbers and detours international

You can get a number in over 40 countries free to assign your own IP telephony. Not only that, they can also create diversions from the number they say in over 40 countries. It has never been so easy to avoid the costs of international calls or have a presence in other countries. You can hire a number in United States for example and allocate it to your IP telephony or divert it to a number in another country. I called there and it sounds here, as simple as that.

VoIP Service - Voip Phone Service - Internet Phone Service

VoIP, or Voice over Internet Protocol is a relatively new service offered by phone that lets you use your computer to make voice phone calls. The service, while new, is wide and is available in many areas in which we already have ADSL and cable Internet connection. Unless you have been hiding under a rock somewhere in Timbuktu, chances are you've heard the term 'VoIP' (pronounced voyp) or Voice over Internet somewhere along the line. So what is VoIP and how is it revolutionizing the way we talk and the phone? Read on for more information.

VoIP phone services

VoIP allows voice telephone calls over the Internet through your Internet connection. VoIP converts your voice to a digital signal that can travel over the Internet to reach the destination where it is converted back to a voice signal. To use VoIP you need to have a high-speed Internet connection, also known as a broadband connection. However, you do not need any special equipment, just your regular home telephone and a special adapter for your phone that will change the signal your voice. You can connect your regular telephone up to your cable model or through the adapter and send calls as usual. Furthermore, there is no limitation on the number of phones that can connect to VoIP.

With connection to standard home telephone, cable modem or the adapter, you just make phone calls as you normally would with your regular phone. You mark the same sequence of numbers and there are no special instructions you need to remember, just take your phone and dial the number you are calling. The call will sound just like a regular ring of the word, you can speak and listen in the same way as you would with a regular phone.

Advantages

A key benefit of switching to VoIP is that you do not have to change phone numbers - in most cases you can keep your old phone number and end up switching providers. Reduced prices for telephone services is also one of the great advantages of using VoIP phone services because of the way in which service companies rated their VoIP phone calls, it is much easier to talk to people all the world in having an Internet connection. You can also talk to more than one person at the same time with VoIP phone services at no additional cost.

You can use VoIP even when your computer is not on the time your Internet connection is direct. This can result in energy savings in their lives, because you do not have to leave the operation of the computer to use your VoIP phone service.

You can use VoIP even when you travel, always having access to an Internet connection and high speed it has taken you to your driver. You can use your VoIP on any regular telephone where they also have access to high speed internet.

You can also receive calls from your phone anywhere in the world you are traveling if you have connected your VoIP adapter to a phone line and Internet connection. This means that you do not have to miss your phone calls from his home, when you are on vacation or on a business trip.

Disadvantages

The most common disadvantage with VoIP is calls being disconnected or having a connection problem due to slow Internet connection is reliable or not. You must have an Internet connection of at least 90 Kbps to ensure good voice quality while using VoIP. Another disadvantage is that your VoIP phone will not work in a power outage or if they do not have Internet services.

Another drawback to VoIP phone services is dependent on having an Internet connection. The quality and reliability of the telephone connection through your VoIP telephony service is based on reliability, speed and quality of Internet connection you are connected. Unfortunately, that means that poor network quality will mean reduced quality in your calls and can cause problems such as echoing during your phone call.

There is a problem with 911 calls to emergency services made using VoIP - the calls can not be traced geographically as they are the regular telephone land lines. To the caller who makes a 911 call must be able to give an address, or there is a possibility that the 911 will not be able to find the location of the call.

Programming

With some programming providers, you get free calls to other subscribers of the same service, regardless of its distance. This may mean a great deal of savings for long distance calls, if the people with whom you speak most often is part of the services. Some providers charge for long distance in a minute or per call basis, much like the way your regular phone brand. Other providers offer a flat rate with limited or unlimited minutes, so you pay a price for however many minutes are offering packages.

There are still other providers which allow you to choose an area code different from where you live to keep their telephone area code. This means you could make free long distance calls to people who want the area code, regardless of location. If you talk to a lot of people in a given geographical area that is outside your area code, you might consider switching to that area code for your VoIP phone service to help save even more money.

Cost savings with VoIP service

VoIP decrease your telephone bill for many reasons. VoIP is cheaper than regular phone services, VoIP providers in the first place because they do not pay taxes or access fees as regular telephone service. However, it is important to note that if you spend less than $ 50 a month on your phone bill, you can not tell heavily on the savings in his account of the phone. You will also save more if you already have an Internet connection to high speed.
