I'm setting up SIP trunks on a CME system using sip phones. I've updated the IOS to c2900-universalk9-mz.SPA.157-3.M8.bin to take advantage of SIP tenant profiles. The SIP trunk appears to be up and registered.
CME#show sip-ua register status tenant 2000
Tenant: 2000
--------------------- Registrar-Index 1 ---------------------

The SIP provider has provided a test phone number. When I call the number I receive a fast busy signal. Debug ccsip messages is showing that the provider is sending the username in the INVIITE Req-URI field and a debug voice dialpeer shows nothing matching as a result. I have talked to the provider and they basically said that's how they send INVITES to all of their customers and that the TO field is correct in their header. They won't change their headers and I need to adjust my SIP headers accordingly.
There is a Cisco ASA in front of the Cisco 2900 CME router. The provider is listening on udp port 5065. The CME is using 5060. I've created SIP profiles based on online documentation, but I'm not having any luck. It doesn't look like the inbound SIP profile command is picking up the call. I'm attaching a config and a few debugs so that maybe a few new sets of eyes can see what is going on. I appreciate any assistance. thank you.
