I recently picked up a client that is using an STSe system. I recently cofigured 2 new users (added their name was about it.) They were able to configure their voicemail box, but I am unable to get their phone to roll to the voicemail box at all, if their on the phone, or like all of the other phones in the office (total of 11 in the office)

I'm not sure which version of the voicemail they have, so I guess what I'm asking is:

1. How can I tell the voicemail type?
2. How can I tell if there is a voicemail group, and if that's the method being utilized (or is there another method)?

I hve the installation manual and the quick start guide, but don't have the technical manual. Also - To my knowledge, they do not have the modem option connected.

Any help would be greatly appreciated.
