METHOD AND APPARATUS FOR COMMUNICATION BETWEEN A SECURITY SYSTEM AND A MONITORING CENTER
摘要:
A method for providing communications between a system control panel at a premises and a central monitoring center comprises transmitting an event code from the control panel to the monitoring center utilizing a first communications format and a network protocol, and causing the control panel to enter a call-back mode. The control panel is enabled to receive in-bound calls utilizing a second communications format. A two-way voice session is established utilizing the second communications format between the monitoring center and the control panel. The two-way voice session is initiated by the monitoring center.
