US Patent:

20060182255, Aug 17, 2006

Filed:

Feb 11, 2005

Appl. No.:

11/057288

Inventors:

Carleton Luck - Apex NC, US
Louis Pratt - Holly Springs NC, US
Craig Miller - Raleigh NC, US
Roger Beathard - McKinney TX, US

International Classification:

H04M 7/00

US Classification:

379220010

Abstract:

Registering with a call manager includes connecting to a first call manager and a second call manager. The endpoints register with the first call manager and send keep-alive signals to the first call manager and the second call manager. If a failure is detected in the first call manager, the system initiates a failover process. The endpoints re-register with the first call manager when the first call manager regains operability.

International Classification:

H04L 12/66

US Classification:

370352

Abstract:

In one embodiment, a Session Initiation Protocol (SIP) endpoint device unregisters all lines from a call manager component. This is followed by a power-on reset. A server is then accessed to read a configuration file of the SIP endpoint device. Finally, the SIP endpoint device re-registers all lines with the call manager component. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.

Carleton Luck - Apex NC, US
Louis Pratt - Holly Springs NC, US
Christopher Pearce - Dallas TX, US

International Classification:

H04M 7/00

US Classification:

379221130

Abstract:

A method to be executed in a session initiation protocol (SIP) environment is provided that includes initiating a conversion process that involves a change from a first communications platform to a second communications platform. One or more routing tables associated with the first communications platform are then dumped. A conversion script is executed such that one or more patterns associated with a dial plan corresponding to the second communications platform are provided in a dial plan format. One or more files associated with the dial plan are loaded into one or more endpoints that are designated to change to the second communications platform.
