Wouldn't you like to have an intercom at all your exterior doors. But instead of having a seperate intercom system, wouldn't it be nice if it was tied in to the phone system, so that you would be able to speak to whoever is at the door, from any telephone in the house. Well our Door/Tel systems allow you to do this. The system will ring the telephone(s) whenever a door bell is pressed, and also allows you to unlock any door from any telephone. You may even have the added feature of having the system call you when you are not at home, at any other telephone when someone rings your door bell, allowing you to speak directly to that person from anywhere!
