Abstract

Automatic caller switching in a cellular voice call. A first voice call may be initiated between a first wireless user equipment (UE) device and a second UE via a cellular network. An indication may be received to switch calling parties for the first voice call. A second voice call may be established between the first UE and the second UE via the cellular network in response to the indication to switch calling parties for the first voice call. The calling and called parties may be reversed (switched) for the second voice call relative to the first voice call. The first voice call may be disconnected.
