Hi all,

I'm trying to configure a Kamailio server, and am having trouble getting devices behind NAT receive calls. Looking at a SIP trace, nothing is being received by the end point, even though Kamailio seems to be sending out a response.

I've opened up my firewall rules, so that shouldn't be an issue.

If I call another endpoint which is behind the same NAT, it works (although no audio), and looking at the trace, the SIP messaging is coming from the Kamailio server (ie. not the other endpoint).

I've even tried using the default kamailio-advanced.cfg & kamailio-basic.cfg both of which didn't work either.

I've attached the current config I'm working on, if someone could please have a look through it, and see where I'm going wrong I'd highly appreciate it.

Thanks

Adnan
