Also, a GSM dialler is quite old fashioned and expensive, requiring a mobile call every time it needs to communicate. You want a 'polled' GPRS/ethernet type system such as Permaconn, Telstra Secure, Fratech Multipath or Emizon (I've listed 'em in random order to avoid fights). They have a fixed monthly fee and do not require a phoneline, plus have better security than phoneline based monitoring.
Where are you located?
