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();

Hello,

hmm, some confusion there. So the request is sent over tcp, but the record route doesn't have transport=tcp? What function do you use to send the request out?

Cheers,
Daniel

Hi Daniel,

To answer your earlier question, Kamailio receive the request via TLS, but need to forward the method to endpoint device via TCP with those Record-Route entries.  I used record_route_preset() but that broke my call so I ended up using appened_hf to get around this problem.

No, you should use either record_route() or record_route_preset(), not both of them for the same request.

Cheers,
Daniel

One other question.  Do I need to run record_route() after I run record_route_preset(string1, string2)?  I tried this and the Record-Route doesn't show presets I defined.

So the ingress is actually TLS -> our VIP address and I see that as the second record.

The first record shows the physical interface of the system with no transport value so it's always defaulting to UDP.  I need to set this particular header to use transport=tcp so subsequent UPDATE messages from the server will use TCP throughout the call.

What is the actual goal? If one of the RRs is generated by an ingress
out of a TCP listener, it should already have ;transport=TCP in it.
