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.

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.

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(); On Mon, Feb 13, 2017 at 10:16 AM, Daniel-Constantin Mierla < miconda(a)gmail.com&gt; wrote: -- Andy Chen Sr. Telephony Lead Engineer 415 516 5535 (M) achen(a)thinkingphones.com

So how do I define what is used? Again when I did call "record_route" I need one of the records to have "transport=tcp" param and not the default UDP.
