[SR-Users] kamailio asterisk

Hello,

can you send the REGISTER request received by kamailio and your config
to me?

As you receive it over TLS, you can get the register by adding the next
line in kamailio.cfg at the beginning of request_route:

xlog("received request: [[$mb]]\n");

I will like to double check if the issue is still present.

You should upgrade to 4.2.3, because it is the latest stable, you have
4.2.1 and there were many fixes meanwhile.

If you preserve sips as uri schema, then you force tls further for
forwarding. You should change that to sip:domain...

Cheers,
Daniel
