[OpenSIPS-Users] Problem in handling BYE using topology_hiding_match()

[Bogdan-Andrei Iancu]

Hi Ravinder,

As per the trace, the ACK is properly routed (frames 17 & 18). Also the 
incoming BYE (frame 19) is forwarded after a long time (see frame 22), 
still there is a funny 501 reply for BYE (before the relay) in frame 21.

Could you also post somewhere the OpenSIPS logs (level 4, debug) 
corresponding to processing the incoming BYE (from 19) ?

Best regards,
