You can add a fixed cellular terminal to your WisDom to provide it with a dial tone. We have these for sale on our site. See the "Cellular" category on our store for more information. Just activate the fixed cellular terminal, plug it into the WisDom with a standard phone cable, and you now have a dial tone available for the WisDom to call you with.
A note regarding broadband monitoring:
The WisDom system is capable of being monitored by a broadband alarm monitoring company; however, we do not recommend monitoring over a broadband internet connection because of the downtime and false alarms that can be caused when your ISP goes down (often at night) to perform upgrades.
Clarification regarding using a fixed cellular terminal with an alarm monitoring company:
The SX5E can be used with alarm monitoring services. The SX5T might be able to be used with monitoring services, if your cellular provider supports "circuit-switched data" in your area. The FWT2006 cannot be used with a monitoring service, it is a voice-only unit. NOTE: Also, there is a GSM add-on module for the WisDom that is coming out in a few months, and that will also give the WisDom cellular functionality. This unit will be compatible with alarm monitoring services. You would purchase service for this through a GSM cellular carrier, such as Cingular or T-Mobile.
