Hello! Two bugs were detected during calls to sbc by user behind NAT Bug 1: UserA is behind NAT and has local IP 192.168.1.101. Sems and userB have external IPs UserA call userB and he answered. After conversation userB made hangup and sbc recieved BYE from him (leg B). This BYE was routed to the leg A but destination IP was chosen incorrect. BYE was sent to local IP instead external IP of userA
Bug 2: The same situation which was described above. BYE was sent to the incorrect IP and there is no any answer on it. As a result sbc makes retransmits of BYE messages. The problem is that sbc did not answer 200OK to BYE on the leg B as a result userB makes retransmits of BYE messages Trace attached. Regards, Artem
