New to the RTC Client API version 1.2 are call control features that allow traditional PSTN-type call controls such as forward, hold, and transfer (or refer). The call control features listed below are available on the IRTCSessionCallControl interface.
|Hold||Places an existing call on hold. If the call is already on hold, the session state does not change. This allows the user to place a call on hold when a new call comes in and then switch between the two calls.|
|UnHold||Places an existing call off hold and returns it to the connected state.|
|Forward||Forwards a call that is in the incoming state.|
|Transfer||Transfers an existing call to another user.|
