I see. FS complains about no transport protocol and gives a 503 with a header like that.
Shouldn't they default to UDP in the absence of a transport parameter? It seems they
are not honoring the quotes.
In this setup Kamailio handles NAT traversal and forwards the registers to Freeswitch.
This works:
Path:
<sip:a.a.a.a:5070;lr;received="sip:b.b.b.b:5185;transport=tcp";transport=udp>
This does not:
Path: <sip:a.a.a.a:5070;lr;received="sip:b.b.b.b:5185;transport=tcp">

Freeswitch doesn't like the transport protocol inside the quotations
and refuses to route a call to the registered user.
Constructing the header manually without the quotes such as:
append_hf("Path:
<sip:$Ri:$Rp;lr;received=sip:$si:$sp;transport=$pr>\r\n");
solves the problem.
Is there a reason for the quotes?
without the quotes ;transport=tcp would become param of the path uri.
