Need to block offnet call transfers - Cisco Callmanager Express

Please excuse my ignorance but I have a client with Callmanager Express and Unity VM? Someone is routing calls through it to Jamaica and I want to block the ability to transfer calls outside of the system. I think someone is calling in and then routing back out through external transfer but I am not sure. Under the call log it reports Originating Number =       918765628831 Terminating number = 918768778631. I found there is a setting to block offNet to Offnet Transfer service paramenter, but it says to go to the Cisco CallManager Administration, this is where I am lost. I have an IP and link to Unity, but I think that is just for VM, not the Callpilot module or interface? I will perform a netscan but what is the normal method to get into CM administration?

I am not able to find or log into Cisco Unified Call Manager Express GUI to make this change, if in fact, that is where I should do so.



Thanks in Advance

Marking calls as "off net" is a Call Manager feature.
On call manager express you need to use COR lists to manage Class Of Restrictions. You can simply permit "only" IP phones to make PSTN calls. This will deny PSTN to PSTN, and Unity to PSTN calls.

Did you have a chance to try the COR list?
