CallManager Locations out of bandwidth causes this message, amoung  
other things.  Check the CCM traces... (or next hop address off the  
destination dial peer)

More info on the problem.  This router has two local PRI trunks  
coming in to a 2MFT card.  It also has two CAS (E&M Wink) trunks  
coming into a 2MFT card for long distance and incoming toll free.

The two CAS trunks work fine.  We are able to get incoming calls via  
the CAS trunks mentioned above with no problems.  Also, we have  
another gateway configured on the same callmanager in a similiar  
fashion and all works fine.  This was all working earlier this  
morning.  No known changes occured between when it worked and stopped  
working.

Quite an interesting problem, we have TAC on the line now but thought  
I would see what others think.
