A wireless communication unit ( 101, 200, 401 ), network switch ( 112, 300, 407 ) and corresponding methods facilitate retrieval, routing, and management of on-hold calls (FIG. 4 -FIG. 7 ) within a first communication network ( 103 ) when the unit is operating in a second communication network ( 105 ) that is loosely coupled to the first. The communication unit comprises a transceiver ( 203 ) configured to support an air interface with the first and the second communication network; and a controller ( 209 ) arranged to cooperatively operate with the transceiver to retrieve an on-hold call from the first network via a call leg established to support a handout to and while the unit is operating in the second network. A user interface ( 211 ) and in band signaling over the call leg facilitates management, connecting, disconnecting, etc., of the on-hold calls by the communication unit.
