[SR-Users] Send socket and sequential requests

Hi,

My proxy is bound to a.b.c.d:5060 and secondarily to e.f.g.h:5060.

Most traffic comes into a.b.c.d:5060 and is relayed out that interface. Some initial INVITEs are routed out of e.f.g.h:5060, forced via $fs. The problem is that the Record-Route header still reflects a.b.c.d:5060 and that sequential messages from both ends end up entering and exiting a.b.c.d:5060. Many endpoints don't like that; for instance, e2e ACKs from the caller that come from a.b.c.d:5060 while the initial INVITE came from e.f.g.h:5060 can be a problem in that they are not matched by some UASs.

What is the best way to approach this? Is this something covered by Kamailio's 'mhomed' core param?

Thanks,
