[cisco-voip] MLPP troubleshooting - CUCM 7.1.(2)

Tue Dec 22 08:50:39 EST 2009

That means you've created a loop with the forward destinations.  there 
are basically 2 types of forward loops:

1. offnet - forward destination matches a route pattern, route list, 
gateway, sends call to peer switch, peer switch sends call back.  this 
is countered by monitoring the number of calls in proceeding state per 
DN.  Once call is connected or disconnected then those entries are 
decremented

gateway--->line1(1)--->fwd--->(a)
(a)-->gateway-->line1(2)--->fwd--->(b)
(b)-->gateway-->line1(3)--->fwd--->(c) (etc, you get the picture)

I believe this is the case you are hitting.  THe call is being forwarded 
offnet but the offnet destination is routing the call back to CM.  
Remove the forwarding loop and your call will likely work as desired.

2. onnet
line1 CFA to line2.  Line2 CFA to line1.

This case is pretty clear.
