[SR-Users] Forward SIP request between two Kamailio servers

Hi,?

I have a simulation setup of 4 VMs in Virtual Box - two UAs and two Kamailio servers. The first UA will register to KAM1, and the second UA will regsiter to KAM2. See the Figure below.

UA1<--->KAM1<---->KAM2<---->UA2 int1 int1 int3 int3 int2 int2

I would like KAM1 to forward all SIP requests destined to int3 via KAM2 and vice versa. I am aware of the routing logic in 'kamailio.cfg', but i find rather excessive. Pseudo code of what i'm trying to achieve:

if (is_method("INVITE")) { if(dst_ip == int3) set_next_kamailio_server(KAM2) }

Or:

if (is_method("INVITE")) { if(callee is unkown) ask_kamailio_server(KAM2) }

Thanks for all the help
