摘要:
A presence information system reports proximity presence status to presence subscribers. The proximity presence status conveys how far an individual is from a phone, computer, or any other endpoint through which the individual communicates, how far the individual is from a presence information server which tracks presence changes, or how far the individual is from any other location, such as an office or a conference room. The proximity presence status supplements static presence states such as ‘Online’ and ‘Offline’. As a result, the proximity presence status helps to provide a more accurate picture of the true presence status of an individual. The presence information system may also track and report proximity presence status of mobile users. The mobile user proximity presence status may be derived from cellular position data obtained from a cellular service provider.

摘要:
A method for providing a stateless Session Interface Protocol (SIP) back to back user agent (B2BUA) comprising receiving a SIP message and determining if the SIP message is a SIP request. The SIP request further comprises a request to create an original SIP dialog or a request for an existing SIP dialog. Method further comprises determining if the SIP message is a SIP response. The SIP response may further comprise a provisional SIP response or a final SIP response. Method is suitable for transforming the SIP request, transforming the SIP response, transmitting the transformed SIP request to a new destination, and transmitting the transformed SIP response to a request originator.

A system and method for simplifying Session Initiation Protocol (“SIP”) Back To Back User Agent (“B2BUA”) development by associating different call legs with each other across multiple SIP entities. Call legs may be associated with one another through a common or shared identification.
