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

Is it plugged in? I think I recall unless it's plugged in, it won't register.

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.

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.
