When message flow is: 1. INVITE/180/200/ACK call from client to server 2. in-dialog re-INVITE from server to client INVITE/100/200/ACK 200 OK response message not forwarded.
200 OK not forwarded for INVITE and re-INVITE scenarios occasionally.
In the SIP profile, dialog-aware is enabled.
There is no workaround for this issue.
Fixed the race-condition occurring when 2 response messages are processing dialog lookup.
