Abstract:
A method for managing signaling states in a packet network, comprising:sending a signaling state from a call agent to a gateway that directs the gateway to detect and accumulate specified signaling events generated by a telephone;detecting and accumulating signaling events at the gateway according to the signaling state;notifying the call agent when the gateway detects the signaling events specified in the signaling state by sending the detected signaling events to the call agent;acknowledging the sent signaling events by sending a new signaling state from the call agent to the gateway that directs the gateway to detect signaling events specified by the new signaling state;detecting the signaling events at the gateway according to the new signaling state; andnotifying the call agent when the gateway detects the signaling events specified in the new signaling state.
