In this paper we propose a functional mapping between Java Call Control (JCC) and Session Initiation Protocol (SIP). We show its effectiveness in enabling easy service design and implementation through experimental results. For this purpose, we have implemented a JCC-SIP Resource Adaptor for a Jain Service Logic Execution Environment (JSLEE). In particular, we have used the Mobicents JSLEE, whi...

As a foundation for the definition of bidirectional protocol mappings between the Session Initiation Protocol (SIP) and the Extensible Messaging and Presence Protocol (XMPP), this document specifies the architectural assumptions underlying such mappings as well as the mapping of addresses and error conditions.

The commercial deployment of voice over internet protocol (VoIP) networks (and associated packet switching technologies) has gathered pace in the recent years. However, a major concern with such networks is the issue of the security of networks based on such open standards. Little research has been carried out into examining the options for securing VoIP networks and, more specifically, the imp...

Abstract Several methods in the Session Initiation Protocol (SIP) can create an association between endpoints known as a dialog. Some of these methods can also create a different, but related, association within an existing ...

The Session Initiation Protocol (SIP) REFER extension as defined in RFC 3515 automatically establishes a typically short-lived event subscription used to notify the party sending a REFER request about the receiver’s status in executing the transaction requested by the REFER. These notifications are not needed in all cases. This specification provides a way to prevent the automatic establishment...

This document defines extensions to the SIP REFER method so that it can be used to refer to multiple resources in a single request. These extensions include the use of pointers to Uniform Resource Identifier (URI) lists in the Refer-To header field and the "multiple-refer" SIP option-tag.

The popularity of gateways that interwork between the PSTN (Public Switched Telephone Network) and SIP networks has motivated the publication of a set of common practices that can assure consistent behavior across implementations. This document taxonomizes the uses of PSTN-SIP gateways, provides uses cases, and identifies mechanisms necessary for interworking. The mechanisms detail how SIP prov...
