costomer has a summit ksu. ext 103 always beeps over the speaker when on hook. they take it off hook and it is ok. they can use the phone. they tried a differant phone and it did the same thing. they did tell me the mailbox is full. could that be a warning the mailbox is full. i have never had this happen before. its a rather long drive so i want to get all the info i can before i go out there. thanks. dave

It sounds like the user set up their mailbox with notification, but instead of programming their cell/pager number, they entered their extension number. Since the mailbox has messages waiting, it is repeatedly 'notifying' them by dialing the extension number over and over. First, they need to delete these messages. Second, they need to go into the notification settings for their mailbox and edit or disable this function. It's all user-level stuff.

easy enough. thank you for the help.
