[SR-Users] advertise xxx.xxx.xxx.xxx:5060 is weird

[Sébastien Brice]

Hi Daniel,
of course please find the capture attached.
192.168.3.97 is the local proxy, i want to have it behaves like and edge router, handling incoming and outgoing traffic.
192.168.3.19 (401@) is an user agent and 192.168.3.33 (405@) another user agent.
trying to invite 401 from 405 triggers a behavior i like (RTP and signalling follow same path upstream to the public kamailio)
but it bypass 192.168.3.97, a case i want to avoid.

thanks your for giving of your time.

Seb

Hello,

can you share the pcap with sip signaling for such case?

It will help to see where the packets are sent and what the headers are
including, making it possible to identify what can be done in the config
in order to fix it.

Cheers,
Daniel
