[OpenSIPS-Users] Topology hiding and unsuccessful dialog termination

[Bogdan-Andrei Iancu]

Hi Chen-Che,

Why does the BYE from callee fails and where ? Is it correctly sent to 
outbound proxy? does the outbound proxy sends the BYE to proxy server 
(with on Route hdr) ? does the BYE come back to outbound proxy ?

A more important question - does the proxy server do proxy or acts as a 
B2B ?
