What is VOIP solutions?
Posted on March 14, 2008
VOIP(Voice over IP , is a way of making phone calls using the Internet. VOIP also known as Internet telephony. VoIP utilize a packet switched network, rather than the old fashioned circuit switched public switched telephone network. All of the large telecommunication companies use IP to carry their long distance telephone traffic, so in a way, we all use VoIP whether we realize it or not! Over the last few years, more and more large and medium sized companies have begun using VoIP to eliminate the cost of inter-office calls, and reduce their overall telecommunication costs.
An added benefit of VoIP is that the voice data gets compressed and takes up less bandwidth than a traditional phone call, additionally, silence (which if you think about it, in most telephone conversations, between the two people talking, on average, at least one of them is silent all of the time!) does not get transmitted as it wastes bandwidth!
There are many scenarios where voice over IP can be beneficial and it always comes down to reducing phone bills. With free phone calls to other Internet telephony users, and cheap phone calls to standard PSTN telephones around the world, you are sure to save money.
How is the VoIP call made?
A voice signal from a VoIP telephone systems usually is passed through a VoIP device that converts the regular telephone voice signal to a digital one so it can use a broadband internet connection where it travels to the destination equipment. The digital signal is then converted back to the original voice call.
In simple words , we can say that when the originator calls a number the VoIP adapter logs on to the routing server , which looks up the destination IP number that’s associated with the dialled phone number and it start the connection. If the destination number is not using VoIP technology, and doesn’t have the phone number tied in with an IP number, then it is recognised that the destination number is a Public Switched Telephone Network (PSTN) phone and the call is routed through the PSTN.
