Bi-directional messaging for an emergency services network

The invention includes a communication network that comprises a conforming emergency system coupled to an emergency services network by a media channel. The emergency services network includes a resource coupled to a plurality of emergency services. When in operation, the conforming emergency system transmits an emergency event message to the resource over the media channel. The emergency event message includes a retrieval key. Responsive to receiving the emergency event message and the retrieval key, the resource initiates an emergency event session corresponding with the retrieval key. During the emergency event session, the resource transmits multiple responses to the conforming emergency system. Also during the emergency event session, the resource receives information corresponding with the retrieval key from at least one of the emergency services, and transmits the multiple responses containing the information.
