Dear all, Could you please let me know the behaviour of UAC in the following scenario (RFC3262 doesn't seem to address this behaviour).
Scenario 1: UAC UAS ----INV-------> <---180-------- ---PRACK-----> (Peer didnt respond to PRACK because of some problem) <---200 INV---- ----ACK-------> ----PRACK-----> ?? Should UAC retransmit PRACK ? or Should the PRACK retransmissions stop after receiving 200OK to INVITE? Scenario 2: UAC UAS ----INV-------> <---180-------- ----PRACK-----> (Peer didnt respond to PRACK because of some problem) ----CANCEL----> <---200 CAN---- <---487 INV---- ----ACK-------> ----PRACK-----> ?? Should UAC retransmit PRACK ? or Should the PRACK retransmissions stop after receiving 487 to INVITE?
