MGCP GW appears "unregistered" in CUCM but "registered" in IOS commands

delr
Level 1
Level 1

Hello Cisco Support Community, Im performing my CIPT1 Lab configuring a MGCP GW (C2811 - c2800nm-adventerprisek9-mz.124-22.T4.bin) in my CUCM (8.6.2.22900-9), but I had some issues with the registration of the GW.

The first one happened when I tried to use the Configuration Server method in the GW, at the beggining the GW received a sort of MGCP commands, except "mgcp", so the GW at IOS level never appeared as "registered" in #sh ccm-manager. Fortunately, I was able to solve it only activation the "mgcp" command and the GW appears registered in #sh mgcp and #sh ccm-manager.

However, at CUCM level, even with the "registered" state in the GW, the GW apears "unregistered". I tried:

  1. The following workaround of restarting the Cisco RIS Data Collector Service but didnt work: http://www.cisco.com/c/en/us/support/docs/voice-unified-communications/unified-communications-manager-callmanager/68240-mgcp-gtwy-reg-failure.html
  2. Bind the interfaces for MGCP and didnt work , either: https://supportforums.cisco.com/discussion/11413126/voice-gateway-unregistered


I really appreciate your help or advice.

Regards.

I also attach the output of the following debugs when I performed the no mgcp/mgcp: http://justpaste.it/ktfs

 

Basic Debugs

debug ccm-manager config-download
debug ccm-manager errors
debug ccm-manager events
debug mgcp packet
debug mgcp events

debug mgcp state

 

And the output of the following show commands: http://justpaste.it/ktg0

This is OLD but I was struggling the same issue for a while.

For me it was showing "unregistered" (even so CUCM was able to make changes and restart) because Layer 1 was not active.

 

HQR1#show isdn status
Global ISDN Switchtype = primary-ni

%Q.931 is backhauled to CCM MANAGER 0x0003 on DSL 0. Layer 3 output may not apply

ISDN Serial0/0/0:23 interface
        dsl 0, interface ISDN Switchtype = primary-ni
        L2 Protocol = Q.921 0x0000  L3 Protocol(s) = CCM MANAGER 0x0003
    Layer 1 Status:

Product 	Cisco MGCP T1 Port
Gateway 	HQR1.cisco.com
Device Protocol 	Digital Access PRI
Registration	Unregistered

That happened because my other side was E1,

as soon I changed to T1 on PSTN to match T1 - T1, the layer 1 was active

 

PSTN(config)#no card type e1 0 0
PSTN(config)#
PSTN(config)#card type t1 0 0
You need to reload the router for this configuration change to be effective.

... After the reload
HQR1#debug isdn err

after it went up, I refreshed CUCM and it appeared registered.

Before that I tried RIS collector restart, cluster-wide restart, gateway restart, no mgcp/mgcp, un-bind/bind. shut/no shut --> basically all other forums with the same issue, nothing worked until I matched the other side.
