Hello,

I would like to use Kamailio as a TCP<=> TLS convertor ? Do you think it's possible ?

I have developed a software (which simulate a SIP phone) which can use UDP or TCP (not TLS). I need a SIP proxy to convert TCP to TLS.

For example: UA => TCP OPTION (5060) => Kamailio => TLS OPTION (5061) => OXE UA<= TCP 200 OK (5060)<= Kamailio<= TLS 200 OK (5061)<= OXE

Do you think Kamailio can do that ?

it is possible, Kamailio can do bridging of SIP signaling traffic between UDP, TCP, TLS and UDP as well as in combination of the four with IPv4 and IPv6 (for example you can have incoming TCP on IPv4 to outgoing TLS on IPv6).

For TCP to TLS just load and configure TLS module: http://kamailio.org/docs/modules/stable/modules/tls.html

Be sure you enable listening on TLS socket: http://www.kamailio.org/dokuwiki/doku.php/core-cookbook:3.1.x#enable_tls

Then Kamailio will automatically do the bridging of the signaling once you call a relay function that has the destination over TLS.
