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.

Cheers,
Daniel
