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.

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.
