Abstract
A telephone device such as a speaker phone or message recording device is remotely controlled either as a standalone device or as part of a security system. The telephone device can be controlled by a key fob or other user-operated transmitter that a user actuates to answer a call by speaker phone, end a call, place a call, or control functions of the message recording device such as playing back messages. The key fob transmits a wireless signal that is received and processed by a security system. In response, the security system controls the telephone device. The key fob may control security functions as well. In another approach, the key fob may control the telephone device directly without intervention of a security system. Or, the key fob may control the telephone device via a home automation network.
