We are a school system deploying a new Unified Communications Manager with Unity Voicemail. We will be placing 6921 phones in our classrooms. Some of these clasrooms are shared by two teachers and the plan is to give each teacher a unique extension number and voicemail mailbox. In the shared rooms, this amounts to using both lines on the 6921 and having two mailboxes.
The system is not in and live yet, but we are trying to work through some of the issues we know we'll encounter. One problem that we are trying to solve is how to indicate the presence of new voicemail messages for each user in the room. We are hearing from our vendor that they do not know of a way to indicate message waiting for both lines on a 6921. Unfortunately they have no experience with the 6921 phones, so they are basing this on guesswork. They cannot verify this as their lab is running UCM 6.x. We are installing 7.1, but have rights to upgrade to 8.0 if necessary.
We are hoping that the phone can indicate distinct message waiting for each line in some fashion. The documentation seems to indicate that this might be possible. We are even OK if the message waiting indicator lights for a message in either mailbox and the users would need to pick up their line and check for a stutter dial tone, but we do not know if this will work either. What we want to avoid is a situation where only one (or neither) extension activates the message waiting indicator and one (or both) users would need to periodically check their voicemail mailbox, or pick up the phone to check for stutter dial tone.
Has anyone deployed 6921s in this fashion and know if there is a way to have distinct message waiting indicators for both lines on a 6921? If so, how does it work? Is it a distinct light, or a distinct message on the display?
Any help would be appreciated.
