A wireless network controller supports telephone call between a wireless telephone and a wired telephone. First and second wired communication channels are connected to a telecommunication switch and the wired telephone, respectively. A third wired communication channel is coupled to a radio frequency base station that supports a plurality of concurrent wireless communication channels to wireless telephones. An interface circuit coupled to the first, second, and third channels switches the connection of the first channel associated with the telecommunication switch between the second and third channels, and hence between the wired and wireless telephones. Simultaneous connection to both the wireless and wired telephones is also supported. A conventional line terminating impedance is always presented to the switch regardless of whether one or both of the wireless and wired telephones are off-hook.
