Ring support multiple calls at once. Managing multiple call offer many features, but it is also important to understand the relation between them. In theory, only 1 call or group of calls, referred here as conferences, can be active. Other calls are going to be on hold. A call on hold can not communicate, be it by instant message or voice unless it is activated again. Double click or press Enter to re-activate the call. Active call should have a green icon emblem are be more saturated than inactive calls.

It is useful if you want to notice the person you are transferring the call to before actually transferring it. You put the person on hold, call the second one, then perform an attended transfer. The call will then be removed and considered over.
