It depends on the panel type.
If it uses the ContactID protocol and has a rock solid internet connection and uses then it can work well. ContactID only sends a series of DTMF tones.
There are other alarm protocols out there however - many are essentially modems that establish a dialup connection and these will not work.
Your best option is to move to a ethernet based monitoring solution, AlarmNZ sell an ethernet adapter that plugs into the phone connection on a ContactID panel and converts this to ethernet so it can just be plugged directly into the router. They also support IP based monitoring which most other alarm companies don't do.
Chorus has spent $1.4 billion on making their xDSL broadband network faster and even more now as they are upgrading their rural Conklins. If your still stuck on ADSL or VDSL, why not spend $195 on a master filter install to make sure you are getting the most out of your connection?
