If we're looking for belt and suspenders solutions (when you lose your primary WAN connection and the cell modems are jammed up...) You could also hitch up an analog modem to a POTS line, and then let your paging software dial your cell/home number. You won't hear anything, but the CallerID will let you know that your monitoring system is *desperately* trying to get in touch :-) Rich Brown richard.e.br...@dartware.com Dartware, LLC http://www.intermapper.com 66-7 Benning Street Telephone: 603-643-9600 West Lebanon, NH 03784-3407 Fax: 603-643-2289
