    Call routing in voice enable Network
    (UMT.Lahore, 2005) Uraiza Ali Qaiyumi; 017 Suraiya Jabeen
    It is experience to all of us placing a call over the Internet. And we all haven't had a pleasant experience. An.IP based conference bridge is subject to speech distortions and substantial computational demands due to the tandem arrangement of high compression .^pgegh codec. Decentralized architectures avoid the speech distortions and delay, but lack of strong control and have a key dependence on silence suppression for endpoint scalability. So to improve our quality of voice and to make our telephone system cheap we will use "gall routing". As in IP network we use different routers to communicate all over the world in the same way we do communicate only Voice here with the help of routers. Here we define dynamic route between the routers and do link Foreign Exchange Station (FXS) and we can link through Public Branch Exchange (PBX) when we dial the desired number to whom we want to communicate, the modulation techniques here with routers make the signals in a communicable format and it get communicated with the other router with which it is configured. And by this way we transfer our call through IP whole over the world with Good quality and with no expense. In the near future, Insha Allah we will make a telephone call, it is more than likely that it would be over the Internet or some other packet network. But, what is it that would make this possible? It is a bunch of protocols and standards; and years of research done by organizations all over the world that would bring about this revolution The next few chapters of this project report will discuss this phenomenon in detail.
