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:
MGCP Domain Name: VGW2821
Priority Status Host
Primary Down 192.168.57.7
First Backup Registered 192.168.57.11
Second Backup None
Current active Call Manager: 192.168.57.11
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?
