example

[0461] Example: Subscriber A at POTS1 calls subscriber B at ViPr V1. The following sequence of events occurs:

[0462] 1. UD1 (Mediatrics or any unicast device) receives a request from User_A to connect to User_B.

[0463] 2. UD1 sends an invitation to UAM. The To field or display name in the invitation identifies that the call is for User_B.

[0464] 3. The UAM receives the invitation as an incoming call C1.

[0465] 4. UAM extracts User_B's sip address from the invitation on C1 and initiates a call to C2 to this user by sending an invitation to V1.

[0466] 5. The UAM also cross-connects C1 to C2.

[0467] 6. V1 sees an incoming INVITE from UAM, which is recognized by the SDP as a ViPr class device. Therefore, the software on V1 knows that the peer software can support all the functionality that a ViPr device is expected to have (including replacement / review etc.).

[0468] 7. User_B, eg at V1, replies OK to the invitation.

[0469] 8. The UAM marks the connection C2 ...

Abstract

A teleconferencing system includes a network. The system includes a plurality of nodes in communication with each other to form a conference. Each node having a video display with a display layout, at least one of the nodes individually controlling at least partially the display layout of each node in the conference with a specific format able to be unique for each node. A method for providing a teleconference including the steps of forming a conference with a plurality of nodes in communication with each other through a network. Each node having a video display with a display layout. There is the step of controlling individually with at least one of the nodes at least partially the display layout of each node in the conference with a specific format able to be unique for each node. A teleconferencing node. A teleconferencing system includes a network. The system includes a plurality of nodes in communication with each other through the network to form a conference. Each node communicating only a change to the other nodes when the change occurs. A method for conducting a telecommunications conference between at least three parties includes the steps of establishing a conference between the party. There is the step of making a change to the conference. There is the step of communicating only the change to the parties.
