[SR-Users] SIP routing problem when kamailio uses 2 interfaces

[Gnaneshwar Gatla]

Hello All,

I'm using Kamailio as a Border controller for my VoIP Research project at my
school.
The problem I'm facing is Kamailio routes the traffic to the private network
where my asterisk machine is listening.
The asterisk machine responds to the Kamailio using the public network but
not the private. Is this an issue with Asterisk? If so how do I resolve it?
