Hi Suganya, As per RFC 3261, I think no timers are specified about this scenario.
When 'A' receives the 180 from 'B' it moves to "Proceeding" state, wherein it expects some final response like 2xx - 6xx. Now, it's left to the UA implementation, that how far it has to wait and send the CANCEL. Someone, please correct me if I am wrong. Regds, Somesh S.
