VoIP service is an ideal means of sending telephone calls over IP networks. The Voice over IP works on the principle of converting analog signals to small packets of digital data and then sending them over a broadband internet connection that ultimately connects the users with the service providers. There are several advantages of using this service. The main reason why people acquire this connection is quite straightforward; the expenses incurred while making long distance calls using such a service is low as compared to the traditional phone line connections.
As VoIP service is based on the transfer of digital data, so the service provider can actually do a lot with this technology. Among the most prominent of the services that a service provider can provide are storing of incoming voice mails in the mailbox, sending of email attachments and 3 way calling. Let us consider a scenario in which the user is busy and wants not to be disturbed by any telephone calls. In such situations, the incoming calls can be stored in the voice mail of the subscribers. A person can also send a voice mail as an email attachment which can be accessed on a computer. Then there are plans where up to three people can involve themselves in conference calling. In fact, calling through Voice over IP is far from restricted. The service allows the user to talk to the entire family in one call. Then there are also the options of sending images, videos and voice to people with whom a person is conferencing.
The internet does not differentiate between calls made to a person living next door from calls to people living in another part of the world. The call charges remain the same; such is the benevolence of the VoIP phone service. It is the benefit in price rates that makes people opt for this service in the first place. Moreover the technology is simple and one only requires some simple tools to access the service. An Analog Telephone Adapter (ATA) is provided by the VoIP service provider. This tool helps to convert analog voice to digital samples by use of Analog to Digital Converter. These digital samples are then compressed by the digital signal processors (DSPs). The DSPs make use of codecs for compression and eventually segment ‘voice signals’ to frames that are then stored as ‘voice packets’. The final process involves transfer of these packets in compliance with Voice Communication Protocol or Session Initiation Protocol (SIP).
When these packets arrive at their destination, they have to be decoded; the entire process is carrier out, albeit in a reverse order. The IP packets are decapsulated in compressed data forms. These data are then decompressed to retrieve the original data making use of the same codec that was initially used to perform the compression. The data is then sent through a digital to analog converter that converts it to the original analog voice format for the listener to hear the voice distinctly. So, VoIP service is actually based on a very simple format but requires fast internet service to ensure an effective and soothing calling experience. This becomes all the more important in the context of business VoIP service, wherein the quality of calls becomes a yardstick in determining the expertise of a particular organization.

VoIP – The Ultimate Calling Solution
December 8th, 2009
VoIP which stands for Voice over Internet Protocol is changing the way people think about making long distance phone calls.
VoIP uses technology that can translate analog audio signal, the signal traditionally used for telephone calls, into digital data that can be transmitted over the Internet and translated back to analog at the other end, if necessary. This technology can also be used without traditional phones, bypassing the phone company (and the outrageous fees) altogether. This technology has the potential to completely revolutionize the telephone industry offering a whole range of new choices for the consumer.
It is highly possible that this technology will eventually completely replace the traditional phone system.
There are several ways to take advantage of this new technology including both pay and free services available through the Internet. Some require purchasing new equipment to make and receive phone calls with a traditional telephone and others make and receive calls through your computer using the speakers and a microphone.
There are advantages and disadvantages to both methods with the computer method being available for free, but requiring your computer to be on and connected to the Internet in order to make or receive calls and the traditional phone method usually requiring the purchase of additional equipment and a monthly usage fee. Even with the fee, however, in most cases VoIP would prove to be a considerable savings over the standard telephone company’s bill.
Actually, there is a good chance you are already using VoIP technology without even knowing it. Many of the big-name long distance telephone service providers are already streamlining their networks using VoIP. This technology takes advantage of sending information electronically in the form of packets instead of the traditional method of circuit switching.
By using packets the information is sent only when it is created as opposed the circuit method which leaves a circuit open for the entire duration of the phone call so that there is a constant flow of information in both directions even when only one person is talking or when nobody is talking at all. Since the packet-switching method only sends actual data as it is created there is much less information “traffic” making the whole system much more efficient.
VoIP phone plans usually include all the premium services such as call waiting, caller ID, call forwarding and three-way calling in their one low (or free) fee rather than charging extra for each of these like the regular phone companies do. This provides yet another advantage for the VoIP customer.
There are even more premium features that go beyond what a standard phone company is capable of, such as filtering calls and routing specific phone numbers to either another number or a predetermined recorded message. Imagine sending all telemarketers to a “this phone is no longer in service message.”
The only potential drawback for some customers is not having access to a high-speed Internet connection. This can pose a problem for close to 50% of Americans who are still forced to use traditional dial-up connections. For the other 50%, however, VoIP is a viable alternative to the high phone bills and lackluster service they have been getting for years. The technology is still in its infancy and its popularity is likely to skyrocket in the coming years.
