7.2. Alarm Systems and TV Device Phone Links

Certain modern appliances like to "phone home" for a variety of reasons. Most common are monitored alarm systems that use a telephone link to report a problem. Satellite TV and digital recording services such as TiVo, that allow you to order Pay Per View movies by clicking your remote also have a phone connection to send the request upstream and receive the authorization back from the TV provider.

If you forget about these services and replace your existing traditional telephone service with a broadband phone, you may have an unpleasant surprise one day. I just hope it's the lack of a movie rather than a lack of police response if your home is invaded.
