Dear All,


Ive been trying to get my VGW (Voice Gateway) registered with my CUCM_7.1


I need to add the isdn bind-l3 ccm-manager in my serial interface. BUT THIS COMMAND IS NOT SUPPORTED

The only command similar to this is isdn bind-l3 q931.


I tried changing the IOS from c3825-spservicesk9-mz.124-15.T10 to c3825-spservicesk9-mz.124-24.T and it gives me nothing.


Ive checked the document - https://supportforums.cisco.com/docs/DOC-2682 and it says that a bug CSCed15644 is acting up. Ive tried to do the resolution steps and still I end up in vain.


Looking forward to all your suggestions urgently.


Regards,

Shabeeb

the commend "service mgcp" allows you to bind l3 to cucm otherwise without the "service mgcp "on the controller configures it as h323 and so the bind l3 back to cucm is not allowed since the iOS thinks you are configuring the controller as h323

Just to try my luck, I even tried with IOS - c3825-adventerprisek9-mz.124-24.T2.bin

Its still the same.

what i did was the following -


initially - the controller was configured as pri-group timeslots 1-31


i changed this into pri-group timeslots 1 - 31 service mgcp


The command appreared and pretty much working fine now..
