The Callcentric SIP Softphone
SIP or Session Initiated Protocol is one of the most popular methods of Internet telephony today. Wikipedia defines SIP as an application layer control (signal) protocol for creating, modifying, and terminating sessions with one or more participants. Such sessions include not only Internet telephony, but also other applications such as multimedia distribution and conferencing. With many easy features, SIP is widely used today in VoIP or Voice over Internet Protocol.
SIP offers the following convenience to the users:
– It is extremely lightweight and simple to use
– it is independent of transport as it can be used with a variety of applications such as TCP, UDP, ATM and so on,
