VG Best Practice

[chuck47172]

Is it best practice to "shut" unused voice-ports on a VG when MGCP is involved and there is no config on the port in CUCM?

If yes, why?

Any comments would be welcomed.

Hi,

My personal recommendation is shutdown all the unused ports on the gateway. I had occasion where the gw cpu went high due to these units used ports we're trying to register with call manager.  I had spent lot of time to get the bottom of it and finally put all these ports manual shut down. The CPU gone low. 

Regards,

Shalid.

I agree with your assessment.

Can you point to a Cisco document that backs up what you are saying?

We are using MGCP rather than SIP.

A coworker said "if there are no DNs on the MGCP configuration in CUCM, delete the ports from CUCM; don’t shut the ports on the gateway itself."

I found that if a port is deleted on CUCM, the VG will still register to CUCM.

I want educate my coworker with a Cisco best practice document that references MGCP configured voice gateways.

Thanks for your response.
