[SR-Users] Kamailio 4.3.4: receive_msg(): no via found in reply

[Daniel-Constantin Mierla]

Hello,

what would be relevant here is seeing the INVITE request sent to
10.14.0.1:5060 -- paste it to the mailing list discussion. That is going
to be used to generate 487, and the Via stack from it should be used there.

Cheers,
Daniel
