Filed:

Nov 12, 2014

Appl. No.:

14/538872

Inventors:

Jon P Davis - Malvern PA, US
Lynnette K Evans - Malvern PA, US
Richard L Fuller - Malvern PA, US
Gregory J Small - Malvern PA, US
Scott S Preston - Malvern PA, US

Assignee:

Unisys Corporation - Blue Bell PA

International Classification:

H04L 29/06
H04M 7/00

Abstract:

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.
