A method of operating a wireless communication system (101) including
initiating
(S402) a call from a first communications unit (120) to a second
communications unit (130), embedding (S404) a push-to-listen control
protocol configuration in a data packet (140) responsive to the call initiation,
transmitting (S406) the data packet (140) from the first communications
unit (120) to the second communications unit (130), configuring (S412)
the second communications unit (130) based on the push-to-listen control
protocol configuration and transmitting (S418) an automatic reconnect from
the second communications unit (130) to the first communications unit (120)
responsive to configuration of the second communications unit (130).
