[cisco-voip] Cisco 2821 & Nortel MICS Back-to-Back (PRI) Issues

based on this line:
Jun  6 12:08:57.771 EDT: ISDN Se0/1/0:23 **ERROR**: Ux_Status: STATUS call state mismatch with invalid cause: cause 0x63, state 0xA, peer state 0x3

I suspect you might be hitting an issue here callerid is provided in an unsupported IE. that causes a status message. that status message contains a call state. the call has already progressed beyond that call state so you get a mismatch, no mechanism for recovery, and a drop.

If the 2821 were using MGCP back to CUCM then this would be relevant:

As is, we need to confirm this is what is happening and then look to our IOS Voice participants for any available options.

You say "outgoing call from perspective of MICS" - is it configured to send name outbound? can you get 'debug isdn q931' in addition to the below? What is the ISDN switch type? sharing as much of the config as you are comfortable with would help.

*if* it is callerid causing the problem you might try disabling callerid under the voice port. I think it's 'no caller-id enable' under the voice port.

I've got a Cisco 2821 with a PRI card configured with SIP trunking. I'm trying to interface with a PRI card on a Nortel MICS. Incoming calls work fine, but outgoing calls (from the perspective of the MICS) ring and die a half second after the called party picks up.

I've including some debug, but not sure what's relevant (I'm not a TDM guy) so let me know what else you need...
