An interface for channels that can be made conceptually part of a Conference, and can then be detached from that conference. This is primarily intended for cellular calls, where conferences consist of several 1-1 calls which can be combined and later detached one by one. (Other services, such as PBXs, might have similar behaviour and could also implement this interface.)

A channel with this interface can be merged into an existing conference by calling MergeableConference.Merge on the existing conference. Once part of a conference call, the channel will appear in the conference channel's Channels property. To split it back out, call Split on the member channel.
