SYSTEMS AND METHODS OF DISTRIBUTED SILO SIGNALING

摘要

The embodiments described herein recite a telephone communication system used for handling information such as messages, typically voice mail messages, and, more particularly, is directed to a system that provides distributed session initiation protocol (SIP) silos. Distributed SIP silos (DSS) is a Communications Application Platform (CAP) feature that maintains the site's call capacity even when a signaling server fails. DSS uses multiple non-redundant signaling servers to provide SIP signaling for the same set of media ports. Because there are multiple signaling servers providing signaling for the same set of ports, the failure of one signaling server only terminates the calls it was actively processing and once those calls have been cleaned up, all the available (non-suspended) ports in the configuration are available to the remaining signaling servers.

1. A computer-implemented method comprising:
establishing, by a signaling server, a real-time transport protocol (RTP) session stream for a call between a media server and a remote endpoint using a port; receiving, by the signaling server from a host server, a command to end a call; transmitting, by the signaling server to the media server, a command to release the port of the call; receiving, by the signaling server from the media server, an acknowledgement of the command to release the port of the call; transmitting, by the signaling server to the remote endpoint, a command indicating the call should end; and receiving, by the signaling server from the remote endpoint, an ok message indicating the command indicating the call should end was received.
