With help from "mark_06" here on Experts-Exchange:

http://www.experts-exchange.com/Networking/Telecommunications/IP_Telephony/VoIP/Q_26599182.html

I've been able to get my CME 3.1 registered to the SIP provider BroadVoice.  I can place and receive calls using their services, with the calls even showing up in the activity log on my account there.

Unfortunately, I have absolutely NO audio at all using their service in either direction.  Inbound and Outbound calls cannot hear each other at all through that service.

I have all internal SCCP phones (4x 7960s and 1x 7920).  These phones work great between themselves, and outbound through the FXO port here in Japan.  Everything works great...  Except the SIP provider problems I'm describing here with BroadVoice.

Would somebody be able to point me into some troubleshooting steps, in order to get audio through the SIP trunk?

Please be patient, as I'm not a voice guy.  I've posted the current scrubbed config below of my 2621xm.

ok this is normal when you use nat with SIP.


Change the 10.0.2.241 to DNS hostname and that should work.

The 10.0.2.241 is my internal exchange server.

I was utilizing Unified Messaging, but for some reason that has stopped working all together once I changed the mwi server in the sip-ua configuration.  I had the destination pattern of 5000 for voice mail, but now the CME dials 5000 out on the FXO port.  I really have no idea as to why.  Once I figured out why the audio wasn't working here, that was gonna' be my next major issue to tackle.

But as far as doing NAT with the SIP traffic on BroadVoice, I'm not.

I've got that all setup through dns hostnames, and on my sip ua bindings, I'm having them utilize my Dialer 1 interface, which is my external static IP.  No NAT or firewall at all.

However, my internal SCCP phones are NAT'd.  With the termination point being at the CME router.  All the SCCP phones are in my internal network.  If that's what's causing the problem, how do I get it working?

(btw - thanks for the reply - it's much appreciated.)

Aparently it was some sort of issue from the SIP provider.  Not sure, but I didn't change anything, and it all works great now.

Thanks for the assistance.
