Method and apparatus for a sip client manager

A method for communicating a message, comprising the steps of:

• receiving, in a SIP management module, a SIP message;
• determining session context information associated with said SIP message, said session context information including message routing information;
• storing said message routing information, wherein the stored message routing information is used when sending a response signal;
• removing said message routing information to form a simplified SIP message and forwarding said simplified SIP message to a first X-SIP client module;
• wherein said SIP management module forwards information to a plurality of X-SIP client modules;
• wherein at least two of said X-SIP client modules are interfaced to client applications operating under different programming languages and having different client application message formats.

A data processing system for communicating using a text based communication protocol, the data processing system comprising:

• a first X-SIP client module containing
• first receiving means for receiving a first request,
• first generating means for generating a first simplified SIP message from said first request, and
• first sending means for sending said first simplified SIP message to a SIP management module;
• and
• a second X-SIP client module that is different from said first X-SIP client module, said second X-SIP client module containing
• second receiving means for receiving a second request,
• second generating means for generating a simplified SIP message from said second request, and
• second sending means for sending said second simplified SIP message to said SIP management module;
• wherein said SIP management module processes said first and said second simplified SIP messages from said first and said second X-SIP client modules;
• wherein at least two of said X-SIP client modules are interfaced to client applications operating under different programming languages and having different client application message formats.

A computer program product in a computer-readable medium for use in a data processing system for communicating a message, the computer program product comprising:

• in each of a plurality of X-SIP client modules:
• first instructions for receiving said message;
• second instructions for creating a simplified SIP message containing said message;
• and
• third instructions for sending said simplified SIP message to a SIP management module;
• and
• in said SIP management module:
• fourth instructions for receiving said simplified SIP message from said plurality of client X-SIP modules;
• and
• fifth instruction for creating and forwarding an expanded SIP message from said simplified SIP message;
• wherein at least two of said X-SIP client modules are interfaced to client applications operating under different programming languages and having different client application message formats.

A data processing system for communicating using a text based communication protocol, the data processing system comprising:

• a network interface;
• and
• a client manager, wherein the client manager comprises a plurality of X-SIP client modules, each said X-SIP client module receiving requests from a respective client application, and SIP management module that communicates with said plurality of X-SIP client modules;
• wherein at least two of said plurality of X-SIP client modules are interfaced to client applications operating under different programming languages and having different client application message formats;
• wherein messages that are passed between said X-SIP client modules and said SIP manager module are simplified SIP messages containing no message routing information.
