Voice over Internet Protocol (VoIP) is simply a form of technology which enables its users to make telephone calls using the wide-banded broadband Internet instead of the regular or older analog telephone system. With a GSM Gateway VoIP system also comes with several advantages for many companies. Saving on costs and improving employee productivity.
When we talk about voice quality, two things are generally important to consider. The voice quality itself and the bandwidth provided for voice calls. Since the use of VoIP telephone systems do not use the traditional telephone lines, they are able to transmit their audio data packets straight into the computer which keeps them from being dropped by terrestrial networks. This ensures that voice quality is preserved the same as when we speak through analogue phones.
The advantage of VoIP above and other kinds of communication equipment lie in the fact that VoIP does not use any one network system for delivering its sound data packets. This is in contrast to the traditional telephone system where all the communication traffic passes through one large network. With a VoIP telephone system, you can have a dedicated VoIP phone that connects to the Internet from your personal computer and to your voice over IP server from anywhere in the world. There is no need to rely on a single telephone network for delivering your voice calls. This is actually a rather expensive proposition as it means that you must have either a dedicated VoIP telephone line that connects to your Internet from inside your premises, or a high speed Internet connection that will allow the data packets to be transmitted efficiently.
Another important advantage of Dect Phones is that there are significant cost savings. The cost of VoIP phones is much lower than those for traditional telephone services. In some countries like the US, international long distance calls may be free but this depends on the service provider. VoIP phones also offer a number of cost savings options. For instance, one can choose to pay a pre-arranged call charge, make local calls at fixed prices and make international calls at subsidized rates. All these options reduce the overall operating cost.
A VoIP Telephone system operates by receiving data packets, which are then converted into sound through the use of digital signal processing. The analog voice data is then sent to the speakers of the phone and converted into sound using speaker correction. To receive voices, special voip phones called digital phone converts voice into data packets and transmits these data packets along with the audio voice to the specified network system. The special voip phones called digital telephone also have the capacity to transmit data packets that are received and converted into real time audio signals.
A VoIP Phone system also includes various additional features like, advanced calling features, call forwarding, call waiting, caller ID, conference call and many more. However, before you opt for the VoIP Telephone system, you need to check the market price of the device as the prices vary from time to time. Another way to find a good VoIP Phone system is to check the VoIP supplier and network providers like AT&T, Verizon, Cisco, Altea, etc. who are offering VoIP services in the desired areas?
