The briding to TLS is not the problem, the problem is the brdiging itself as it introduces an intermediate hop which has to take care of NAT traversal and rewriting REGISTER requests to allow proper routing.
There is no receipt to implement this as it also depends on yopur setup and how your service provider does NAT traversal. There was a recent thread were I described steps to take.
Thus I suggest to start with a simple UDP-UDP proxy. And once this works then try TCP/TLS. Further, Kamailio is a low level SIP proxy and therefore you really need to understand SIP and NAT problems (header rewriting) to solve such a setup.

Hi All,
I've been googling for a little while now and although I found others asking the question and answers says "yes it's possible" I haven't managed to find out *how* to do it!
I have a relatively simple scenario where I'd like to use Kamailio (or something else?) to take TCP or UDP connections from my Linksys PAP2T ATA and proxy them to my sip provide which only allows TLS connections (obviously the Linksys doesn't support TLS).
The kicker is that, although I understand the theory and principles of SIP, I'm completely new to SIP software and how to configure it, etc. If anyone can point me to a (good and recent) beginners guide to Kamailio installation and configuration that would also help ;-)
Many thanks
Matt
PS. Installation status is I have Kamailio installed on Ubuntu with TLS configured (define WITH_TLS& module installed), started and listening! I've but not yet enabled mysql (not sure if it's needed for what I want to do!)
