Abstract
In an embodiment, an originating device sends a request, to a server, to initiate a full-duplex session with a target device. Responsive to the full-duplex request, a half-duplex session is set-up from the originating device to the target device before the full-duplex session is set-up. The target device indicates its acceptance of the half-duplex session, receives half-duplex media from the originating device and selectively indicates its acceptance of the full-duplex session. In another embodiment, during a session currently supported either by half-duplex or full-duplex, the server arbitrating the session receives a request from one of the session participants to transition the session to another duplex-type. The server then selectively transitions the duplex-type of the session.
