[OpenSER-Devel] sipp 2.0, VIA sent-by and transaction matching

[Bogdan-Andrei Iancu]

Hi Ovidiu,

I would say this is openser's VIA:

Via: SIP/2.0/UDP 127.0.0.1:5059;branch=z9hG4bK4783.c7afa14.


The via generated by openser, there is a digit at the end (branch 
number)...But here is missing.
Henning, Could you post the request also (sent out by openser)?

regards,
bogdan
