[OpenSIPS-Users] Doubt about provisional responses processing

[Bogdan-Andrei Iancu]

Hi Sergio,

So, for the re-INVITE you have a provisional reply before the 200 OK 
(both replies for re-INVITE). Is this true ? and the 200 OK does not hit 
the on_reply route ?

Do you have a full SIP trace of such a call ?

Regards,
Bogdan
