Hello,
I’m using Kamailio as SIP proxy to receive INVITE packets, randomize
A-number and then relay it to a certain gateway.
I noticed that a Via header is added to the INVITE sent by Kamailio to
the gateway with 0.0.0.0 as address as shown below:
Via: SIP/2.0/UDP
0.0.0.0;branch=z9hG4bK2d97.61de75dd58fa7ca7450cc8b9b01db62f.0
As far as I know, the IP that should be used in the new added VIA
header must be Kamailio IP, but it’s not the case here, knowing that
Kamailio is not behind NAT.
I guess that you have listen global parameter with 0.0.0.0, you have to
listen on the IP you want in Via or add advertise to listen with that IP.
Cheers,
Daniel
