Method and apparatus for establishing communication between two teleconferencing endpoints

A method for establishing communication between two processing endpoints comprising the steps of:

• a. a first endpoint transmitting a first message to a second endpoint indicating a desire to connect, said first message including communication capabilities of said first endpoint;
• b. said second endpoint checking for a timeout value in said first message and notifying said first endpoint of confirmation to connect via a second message;
• and
• c. said first and said second endpoint establishing communication according to said communication capabilities.

An apparatus for establishing communication between two processing endpoints comprising:

• a. a circuit in a first endpoint for transmitting a first message to a second endpoint indicating a desire to connect, said first message including communication capabilities of said first endpoint;
• b. a circuit in a second endpoint for checking for a timeout value in said first message and for notifying said first endpoint of confirmation to connect via a second message;
• and
• c. a circuit in said first and second endpoint for establishing communication according to said communication capabilities.

An apparatus in a first endpoint for establishing communication between two endpoints comprising:

• a. a transmission circuit for transmitting a first message to another endpoint indicating a first desire to connect, said first message including first communication capabilities of said first endpoint;
• b. a communication confirmation circuit for receiving a second message from said another endpoint, checking for a timeout value, indicating a second desire to connect including second communication capabilities of said another endpoint, and responsive thereto, if said first endpoint desires communication with said another endpoint with said desired communication capabilities, for transmitting a third message for notifying said another endpoint of confirmation to connect;
• and
• c. a communication establishment circuit for establishing communication according to either said first or second communication capabilities responsive to a response from said another endpoint to said first message or said desired communication with said another endpoint.
