The mailbox is full.	When a user's mailbox is full, the caller cannot leave a message in that mailbox but is given the option of transferring to another extension. For all users, mailboxes can store up to 180 minutes of recorded messages (or 120 messages, whichever is reached first). The factory-set Mailbox Size is 20 minutes. Instruct the user to delete unneeded messages. Increase the Mailbox Size, if necessary.
The system is full. The user can store a maximum of 100 hours of voice mail messages.	Instruct users to delete unneeded messages.
An Outcalling number is incorrectly programmed, forwarding Outcalling notification to an internal telephone associated with this mailbox. Each time a new message is received while Outcalling is in effect, the system will send the notification to this mailbox according to the specified number of Outcalling cycles.	Verify that Outcalling numbers are correctly entered.
