I'm playing around with a 2951 and a few phones that I have laying around in my basement. Everything works fine with the SCCP calls, but when it comes to the SIP phones, I have outgoing call issues. The system is sending the phones' extension numbers to the SIP trunk. I'm not really sure where to go with this one, because I've always been kind of weak on voice.
It has to be something stupid that I'm missing, but I'm not really sure where to go from here. Incoming calls work just fine. It is not trying to register the phones to the SIP trunk (DNs tagged no-reg). I'm just not sure how to troubleshoot from here. The error message I get with the outgoing call is triggered by invalid calling phone number being passed to the carrier.
I've always likes playing with these "kitchen sink" devices, and learning about the features that nobody really uses. I've only seen CME in the wild about it dozen times.
