First of all, we need to understand your deployment model.

There are many different deployment model on OCS/CUPS/CUCM. The most popular one right now is called "MOC RCC" (Remote Call Control).

In RCC model, MOC controls a Cisco IP phone.

If you're in RCC model and you say "CUPC cannot dial to MOC", that means "CUPC cannot dial IP phone". Is that what you meant?

Or did you mean, CUPC dials MOC-controlled phone. The phone rings but there's no prompting message on MOC?

For more tech tips, please see my blog:




We have a similar lab setup,

CUCM 7.0.1


CUPS 7.0.2

We have dual-forking working (kinda)- rings on IP phone but delayed on the MOC client. Extension numbers are in \+XXXX format.

Problem is now we are trying to use Exchange 2007 for Voicemail but somehow Exchange is not recognizing the number format. Anyone else run into this type of thing?
