Hi All, ** Here are my questions. 1. How can TU know if 408 Request Timeout is generated from stack or UAS?
2. Per RFC 3261 17.1.1.2, when Timer B expires in "calling" state, UAC should not generate ACK. Even though 408 Request Timeout is generated by stack in "proceeding" state, should UAC send ACK to UAS? 3. If 408 Request Timeout is sent by UAS in "proceeding" state, should UAC send ACK to UAS? thanks in advance, Sumin. _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
