When we were on CCM 4.2.3 I had a requirement to setup a group of our Call Center agents so their extension wouldn't show up. I created another partition and CSS and put them in it. There is a 4 digit translation pattern that allows them to get out to the rest of the users. I set the pattern to over-ride the calling number with their main extension. This worked great, even for IPCCx calls and calls to Voicemail
This worked great until we upgraded to CUCM 7.0. Now when they call on their lines the number shows up as it should but if the call is connected with CCX (Also as ver 7.0) or they leave a voicemail, the calling number shows as their actual extension. Did something change with CUCM 7.0 for this kind of configuration or am I running into a bug?
