Now Telephone B, as the conference initiator, holds the three-party conference with the passive
participants Telephone A and Telephone C.
If you also enable three-party conference on the FXS lines of Telephone A and Telephone C on
Router A and Router C, then during the conference, a new call can be initiated from Telephone A or
Telephone C to invite another passive participant. In this way, conference chaining is implemented.
