Off-site message alert works this way:

●Set up off-site message alert by entering the phone or pager numbers at which you want to be contacted. (You can list up to two phone numbers to be called in succession or up to two pager numbers or one of each.)

●Turn on the feature when you leave your office and indicate whether you want to be alerted to all new messages or only those marked urgent.

●The CLASSIC MAIL system calls you “n” times at the first number at regular intervals, where “n” is the number of call attempts you set. (You set the number of call attempts between 1 and 9, and the interval between 5 and 999 minutes.)

●Next, if you specify a second number, the CLASSIC MAIL system calls you there the specified number of attempts.
