Hello,
I have a problem with parallel forking and TCP when one connection isn't
available and the inv_timeout expires.
I have two clients registered with the same username and transport=TCP.
If I make a call to this number when one of them is not reachable, the INVITE
goes to the phone reachable, if the call timeout expires (fr_inv_timer_avp)
Openser sends the CANCEL, but doesn't send anything to the caller.
The failure_route doesn't hit.
There is also a delay between the t_relay and the forwarding of the packet TCP
on the net (around 3 seconds). The TCP packet is forwarded to the available
connection only after Openser detects the failure for the closed TCP connection
(the INVITE goes on the net only after the message ERROR:tm:t_forward_nonack:
sending request failed).
This is the trace (debug level 3, Openser version 1.3.2):
