[SR-Users] record_route() function

[Andy Chen]

So the INVITE coming in (TLS) don't have Record-Route.  When Kamailoi
received the INVITE, I call record_route() and adds the two entry.
However, one of the entry I need to have transport=tcp.  When I added it as
this:

record_route(";transport=tcp")

It adds it to both Record-Route therefore messes up the call.

Kamailio forwards to endpoint device via tcp using the following function:

t_replay_to_tcp();
