public async bool transfer (Cancellable? cancellable) throws Error
Asynchronously joins all active and held calls, and disconnects from them.
When the operation is finished, callback will be invoked in the <link linkend="g-main-context-push-thread-default">
thread-default main loop</link> of the thread you are calling this method from. You can then call transfer.end
to get the result of the operation.
See transfer_sync for the synchronous, blocking version of this method.
