CCM Publisher and Subscriber problem

Hi all.

We have two CCM 4.3, one publisher and one subscriber.

We have a voice gateway, a 2821 router, for pstn connection (with isdn pri).

All works well.

Problems begin if we need to stop primary ccm: when this happen, outside calls work well, but inbount call no.

When primary ccm is down, I can see this output from voice gateway:

VGW2821#sh ccm-manager

MGCP Domain Name: VGW2821

Priority Status Host


Primary Down

First Backup Registered

Second Backup None

Current active Call Manager:

It seems ok, but inbound calls don't work; I can see calls coming in, with debug into router, but CCM doen't route them.

In CCM --> Device --> Gateway

I see vgw in "Not registerd" status (from web management interface in backup ccm).

Maybe I've misconfigured voice gateway? Or CCM?

Re: CCM Publisher and Subscriber problem

does the GW config under the CUCM has a device pool that has under the CUCM group both servers?

you need to configure the backup server under the GW config but also make sure the GW under CUCM has a CUCM group with the servers to which the GW can failover
