I'm wondering how I can configure a Cisco router in a lab to integrate into an existing voip infrastructure running SIP. It's a 2610 XM with fxs ports as well as running CCME sitting behind a NAT router into the corporate network.
The only details i've been provided are the SIP Domain, SIP proxy server as well as a username and password for authentication.
I've tried different combinations of sip server and registrar within SIP-UA config and i've tried binding the media and setup packets to the inside global address of the NAT but i'm not having any luck registering or initiating a call.
I've tried debug ccsip messages already and i'm not receiving any error messages. I'm only seeing it constantly send Register and Invite messages (depending on if i'm trying to use a registrar server or establish a call)
I've several softphone products which can detect the global address themselves and register accordingly, is there anything I can do on the router to achieve the same? I created a loopback interface with the global address and bound sip messages to it but it made no discernible difference.
I'm afraid that if don't see replies back it means the SIP device is not correctly handling the SIP. Even if you set the address via bind, the NAT device will not have a translation set and not let the messages come back.
Unfortunately cisco does not support STUN and similar mechanisms so either the NAT device supports NAT, or you are out of luck.
I can change the domain with the session target in the dial-peer but then its obviously not sending to the proxy server but to the domain. How can I change the domain for the requested address but not change the session target?
I've successfully received incoming calls now with full duplex voice, so everything is sorted out as far as that. There was a minor issue with codecs (Cisco defaulting to G.729 annex A and the networking running G.729b, G.711a, G.711u)

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
