[cisco-voip] Registration rejected on a single FXO port of an MGCP 2801 with a 2FXO card?

Fri Feb 13 14:40:55 EST 2009

What in the world could be causing this?
I've had registration issues with MGCP equipment in the past, being
hostname/domain-name related
That makes the entire device not register.

But I've never seen one port get rejected and the other one not!
Weird.

IP Address 192.168.XXX.252

IP Address 192.168.XXX.252 
End-Point Name   AALN/S0/SU0/1 at TransitGW2801.mydomain.local   

Everything is identical in the CCM (UCM 6.01)
both ports are configured EXACTLY the same way...

What the heck is going on?

That output should ALSO show
aaln/S0/SU0/0 at TransitGW2801

and would show it, I think,  if the port registered.

 DS0 Resource Statistics
 -----------------------
 Utilization: 0.00 percent
 Total channels: 1                       < This would appear to just
confirm the fact that only one port registered, not be a source of the
problem
 Addressable channels: 1
 Inuse channels: 0
 Disabled channels: 0
 Free channels: 1

## Both ports exist--- both are admin UP, with no failures, both are
Loop Start
So it's not something confused with the hardware.
