[cisco-voip] Calls not completing.....randomly

[Jason Aarons (US)]

You'd have to stick something like a TTC T-Berd with a Y-Cable between
the SmartJack/Router and try to catch a call failing if debug vpm signal
doesn't show cause.  Normally a good telco brings out a T-BERD or
similar test equipment, but you can rent one cheap for 30 days depending
on how important solving the problem is <grin>

Another choice is to switch from MGCP to H323 just to see if problem
stops...tried changing IOS ?

Anyone have any clever ideas for tracking down problems with inbound
calls randomly not completing successfully?  Two MGCP gateways with
three T1 CAS circuits per gateway.  All circuits are in a single trunk
group.  Problem isn't isolated to a single DNIS.  Cannot find any
pattern.  When call volume is very high it is impossible to debug.
Since they are MGCP controlled we don't get ANI.

 

Of course Qwest says all is good on their side......

 

Any ideas would be helpful.
