A telephone system for providing a telephony feature includes a phone system controller and a first telephone system interface. The first telephone system interface is coupled between a first telephone handset and a telephone line. Moreover, the first telephone system interface is operable to selectively couple the first telephone handset to the telephone line. The first telephone system interface is also operable to establish a first wireless control channel to the phone system controller. The wireless control channel is operable to carry control signals associated with the telephony feature between the first telephone system interface and the phone system controller. The phone system controller is operable to (i) receive the first control signals via the wireless control channel, and (ii) process the first control signals to provide the telephony feature to the telephone handset.
