Hi All,
Is there an equivalent to corex's send_tcp (https://kamailio.org/docs/modules/5.2.x/modules/corex.html#corex.f.send_tcp https://kamailio.org/docs/modules/5.2.x/modules/corex.html#corex.f.send_tcp) for TLS?
I have a bit of an odd edge case where I can't add Via headers etc, and send_udp and send_tcp allow me to achieve what I want, but it doesn't seem to have a means of doing the same with TLS?
Essentially I want to transparently proxy what is received by Kamailio on one interface to a TLS connection e.g.
A = (TCP) => Kamailio = (TLS) => Remote Host
(A) in this instance is already setting a Via header of the Kamailio's external IP and transport tis. I appreciate this is a non-standard way of doing it, but (A) is a black box that I can't change, what I'm essentially trying to do is have Kamailio handle the TLS but essentially (A) thinks it's at the edge.
I can make it work with send_tcp for a standard TCP connection, but if I use t_relay or even forward() to send onwards by TLS then Kamailio obviously adds its own headers as you'd expect.

I know it doesn't make sense, it's a bit of a stop-gap solution that I had hoped would be simple and turned into anything but ;-)
Best, Ross

you are trying to use Kamailio as transport bridge (TCP <-> TLS) but don't want to use it's transport bridge capabilities (Route & Via headers etc.), that doesn't makes sense...
But nevertheless, i think you can,
Use t_relay and then in "send" event route remove the headers added by kamailio manually using textops module functions.
Use send_data or sendx methods in corex module.
https://kamailio.org/docs/modules/5.5.x/modules/corex.html#corex.f.send_data
- Use "network:msg" route and shape the sip packet to the form acceptable by TCP box.
https://kamailio.org/docs/modules/5.5.x/modules/corex.html#corex.evr.network...
By the way, per my understanding send_tcp suppose to work for TLS connections, since TLS is basically a TCP connection. Anyways, i will run some tests to see its behavior when i have enough time.
