Hi,
After making some tests, I found that if I configure the VIP interface
before the non-VIP one, all works fine.
listen=tcp:VIP:5060
listen=tcp:nonVIP:5060
Double RR is still enabled but only one RR header is added (with the
VIP interface). Also, only one Via header is added (with the VIP
interface). The incoming INVITE is forwarded using a random source
port, not 5060. I assume it is the source port used to establish the
TCP connection with the proxy (next hop from the load balancer).
However, this port doesn't appear in the inserted RR and Via headers –
don't know why.
the source port you see in the network traffic is randomly allocated by
OS/kernel. The addresses in the headers should be those where kamailio
can receive traffic. If the port is 5060, it can be omitted, being the
default value for sip.
Cheers,
Daniel
