Network that provides applications collaboration

A system for providing a communication session over a network, said system comprising:

• a network node;
• at least two endpoints adapted to be coupled to said network node;
• a first database storing two or more versions of a collaborative application;
• and
• a second database storing types of all endpoints adapted to be coupled to said network node;
• wherein said network node:
• receives an identity of a called party and an identity of a collaborative application from a calling party, wherein the calling party participates in the communication session at a first endpoint and the called party participates in the communication session at a second endpoint;
• queries said second database to determine a first endpoint type and a second endpoint type;
• queries said first database and retrieves a first version of the collaborative application based on the first endpoint type and a second version of the collaborative application based on the second endpoint type, wherein said first version differs from said second version;
• and
• executes the first version of the application for use by the calling party at the first endpoint and the second version of the application for use by the called party at the second endpoint.

A method of collaborating on an application, said method comprising the steps of:

• (a) receiving a request to establish a communication session from a first user at a first endpoint, said request including an identity of a second user at a second endpoint;
• (b) determining a first endpoint type and a second endpoint type;
• (c) retrieving first version of the application based on the first endpoint type and a second version of the application based on second endpoint type, said first version differing from said second version;
• (d) establishing the communication session between the first user and the second user;
• and
• (e) executing the a first version of the application so that it is available to the first user at the first endpoint and a second version of the application so that it is available to the second user at the second endpoint during the communication session.
