[cisco-voip] h323 to call manager inbound calls randomly complete

[Scott Irey]

Hello,



Having a problem with inbound calls from TDM completing h323 to cucm 7.1.
Seems to be fairly random, works once or twice, next call fails, cycle
repeats. Doing a debug CCH323 all, here is where a call fails and never
connects…

Repeats this for a bit and then sends a disconnect. And I get operator from
the telco.



Any one seen something like this before where some calls complete and some
don’t?
