Systems, Methods, And Computer Program Products For Providing A Manual Ring-Down Communication Line Using Session Initiation Protocol
US Patent:
2011007, Mar 31, 2011
Filed:
Sep 29, 2009
Appl. No.:
12/569494
Inventors:
Timothy Potts - East Haven CT, US
Leonidas P. Papadopoulos - Ridgefield CT, US
Rajnish Jain - Fairfield CT, US

Assignee:
IPC SYSTEMS, INC. - Jersey City NJ
International Classification:
H04L 12/66
US Classification:
370352
Abstract:
Systems, methods, and computer program products are provided for manual ring-down communication using Session Initiation Protocol (SIP). A first SIP user agent transmits a message to a second SIP user agent over an Internet Protocol (IP) network to establish a SIP session. The first SIP user agent determines that a signal key associated with a first communication device has been selected and transmits, to the second SIP user agent over the IP network, a start event message to cause a second communication device to activate an alert. The first SIP user agent determines that the signal key has been released and transmits over the IP network an end event message to deactivate the alert. The first SIP user agent transmits, to the second SIP user agent over the IP network, one or more subsequent INVITE messages at a predetermined repetition rate to refresh the SIP session.

Abstract:
Systems and methods are provided for setting up persistent, secure communication channels between remote groups of individuals over an unreliable network such as a packet switched or frame relay network. A group, which could be an individual, searches for another group, which could be an individual, through a hierarchical search structure. When the search results in a group that the searching group wants to communicate with, the searching group sends an invitation to the identified group and when the invitation is accepted a persistent communication channel is configured between the two groups.
