Attributes

Remarks

Returns the child Call in a generic conference that is currently active.

A "generic conference" is the mechanism used to support two simultaneous calls on a device in CDMA networks. It is effectively equivalent to having one call active and one call on hold in GSM or IMS calls. This method returns the currently active call.

In a generic conference, the network exposes the conference to us as a single call, and we switch between talking to the two participants using a CDMA flash command. Since the network exposes no additional information about the call, the only way we know which caller we're currently talking to is by keeping track of the flash commands that we've sent to the network.

For calls that are not generic conferences, or when the generic conference has more than 2 children, returns null.
