I have the need for both REFER handling and rtpproxy in the same config.
So, I need both proxy-style and B2BUA-style functions. I'm attempting to
combine them by processing the proxy-style requirements first, use
t_relay() to send the INVITE back to itself, and then initializing the
And it works...almost.
It seems the B2BUA is "eating" the ACKs that should route through the proxy
side. After the B2BUA scenario is initialized I no longer detect them

This is a multi-homed situation with a private and public interface. I've
tried various combinations of public, private and localhost sockets when
routing the INVITE back to itself but the result is the same.
I've tried it with and without dialog module topology hiding. No change in
How does the B2BUA module "know" a packet is for it, rather than for
regular proxy handling?
