A communication system for emergency communication comprises a communication server to establish an IP based voice communication between an endpoint and a monitoring center. In one implementation, the system establishes an emergency call using an emergency communication system comprising a communication endpoint, a communication interface and a monitoring center comprising an automation system and a communication server to establish an IP based voice communication. The system initiates the emergency call at the endpoint location using the communication interface, establishes an IP based voice communication between the endpoint and the monitoring center via the communication server, and automatically sends a message from the communication server to the automation system when the call is initiated.
