Please help with MGCP PRI config

[andysparks]

Hi,
I had a 2801 configured for a single, 24-channel PRI against CM 4.2 working just fine. I decided to move to a new CallManager 8.02 and had to change the mgcp configurations in the 2801 (voip dial-peer, ccm-manager, mgcp ) to point to the new CM.

Now of course I'm stuck because the PRI will simply not come up but is stuck in the TEI_ASSIGNED state. I have tried:
1. resetting the endpoints from within CM
2. no mgcp/mgcp on the 2801
3. shutdown, no shut on the serial 0/1:23

but nothing is good.

Troubleshooting commands
---------------------------

show isdn status
Global ISDN Switchtype = primary-4ess
ISDN Serial0/1:23 interface
dsl 0, interface ISDN Switchtype = primary-4ess
Layer 1 Status:
DEACTIVATED
Layer 2 Status:
TEI = 0, Ces = 1, SAPI = 0, State = TEI_ASSIGNED
Layer 3 Status:
0 Active Layer 3 Call(s)
Active dsl 0 CCBs = 0
The Free Channel Mask: 0x00000000
Number of L2 Discards = 0, L2 Session ID = 4


When I enable debug isdn q931 and reset the PRI from the CM I see

Attaching my 2801 configuration and a screenshot of the CM config.

Any help is tremendously appreciated!

Ugh, discovered I used the wrong model in CM (2801 instead of 1760) for anyone who has a similar problem.
