[OpenSIPS-Users] Problem with 200 OK after BYE

[Bogdan-Andrei Iancu]

Hi Dragomir,

I guess you Topo Hiding on OpenSIPS (I see only one VIA in the BYE sent 
out by OpenSIPS to the SBC) ?

Anyhow, I see nothing wrong with the BYE sent by OpenSIPS. Do you have 
access to the logs/traces on the SBC ?
