How do you stop two user's from signing into a Cisco Unity Connection Mailbox at the same time?

[Ryan Camron]

We have Cisco Unity Connection, and are having problems with departmental(shared) mailboxes. 

We have the same line on 5 phones that access the voice mail box. Multiple users can be in the mailbox at the same time listening to the same message without knowing the someone else is listening to it as well. Is there a  way to limit the system so that only one person can be listening to the messages at a time? If anyone else were to attempt to call in and listen it could state the mailbox is busy or something?

Any help is greatly appreciated....

That's simply not possible AFAIK, you cannot limit how many parties can call to the same mailbox at the same time.

Your problem can be resolved by using Dispatch Messaging feature in CUC.

Dispatch Messages

Dispatch messaging is useful when a team is available to respond to messages and only one member of the team is required to respond.

Following are the ways to handle dispatch messages:

    If a user selects to accept a message, all other copies of the message are removed from the mailboxes of the other members of the distribution list, regardless of whether the other users have listened to or postponed the message.

    If a user selects to postpone the message, it remains as an unread message in the mailbox of that user and in the mailboxes of the other members of the distribution list.

    If the user selects to decline the message, it is removed from the mailbox of that user but copies of the message remain as unread in the mailboxes of the other members of the distribution list.

    If there is only one copy of the dispatch message remaining and no user has yet selected to accept the message, the final user whose mailbox it is in must accept it. That user is not given the option to decline the message.
