MGCP does not show as registered on Callmanager Endpoints

[ed.crawford]

I have configured a 2911 router to use MGCP with Callmanager 8.5. A show ccm-manager on the router shows that it is registered with the Callmanager as does show mgcp, however under the endpoints for the gateway it shows Unregistered.  Is this because I have not plugged the ISDN into the router yet?

Hi Ed,

This is the expected behavior. Once you have your cct. up and running

the endpoints will transition into a "Registered" state

Cheers!

Rob

[ed.crawford]

Great.  Thanks Rob.

[giuseppe.tetti1]

I have same situation, what tou mean when you say "cct. up and running" ?

Thank you very much.

Hi Giuseppe,

How do the endpoints  show in the cucm?

can you please post the output of a show isdn status and a show ccm-manager?

Also a show run | s domain

Thanks

Regards

Carlo

[giuseppe.tetti1]

Dear Carlo,

attached "show ccm-manager", regarding isdn status, we have not yet connected voicegateway to ISDN PRI involved, we are going to do so in the day of migration.

Of course before doing the migration I would like be sure that system has been correctly set up.

Thank you for your kind support.

Giuseppe

Hi Giuseppe,
Until the ISDN layer 2 is not up, you won’t see the up status on the
endpoints.

HTH

Carlo

[giuseppe.tetti1]

It means that endpoints are displaied as unregistered on CUCM ?

See screen capture attached.

[giuseppe.tetti1]

couls you delete the previous attached file please and consider this one.

[giuseppe.tetti1]

Could you delete the previous attached file please and consider this one ?
Sorry about that.

hi,

you can also try Tx and Rx pairs physically short that is 1 with 4 and 2  with 5 to check the status of MGCP registration on Call manager

regds,

aman

[giuseppe.tetti1]

Thank you Aman,

this is very interesting and usefull.

Refards.

Giuseppe

[Carlo Poggiarelli]

That’s correct Giuseppe.

Until the show  isdn status doesn’t show Multipleframe established, they will stay in unregistered status.

Carlo

Thank you Carlo,

this is very helpfull.
