Hi Brian
We are still on V4 because we inherited the system when we moved into this building about 3 years ago. We have no contract with Cisco or third party, and although i'm a 20 year techy veteran, i've had no formal training or long term working experience with Cisco, so even if an upgrade were free (which i doubt), I'm not sure that i'd want to risk breaking a fully functional system.
As for caller ID, this is coming through as a number. I was just wondering if there was a table anywhere, where I could populate frequent numbers with names ?
