At least one of the servers manages the PoC call session by acting as an arbitrator, and controls the sending of the control messages and the voice frames to and from the mobile units. At least one of the mobile units and at least one of the servers use multiple simultaneous connections to the plurality of wireless communications networks to communicate with each other.
