Abstract :
The time for which the phone call can ring should be configurable at the switch. Underlying protocol responsible for establishing the call should provide the facility to configure the ringing time. It has been observed that the SIP phone call can ring for the time indicated by timer B. The timer B controls transactions timeout. If the called party does not answer the phone before timer B expires then the SIP call is not established. This paper suggests modification to SIP protocol as defined in RFC 3261 with respect to its handling of timer B and configuring the time for which SIP phone can ring before the call is disconnected.
