A telephone to be connected to a wireline having reduced sensitivity to RF
interference over a predetermined frequency range from an adjacent mobile
wireless communications device may include a transmit amplifier, a
receive amplifier, an audio input transducer connected to the transmit
amplifier, and an audio output transducer connected to the receive
amplifier. The telephone may further include an RF shield(s) surrounding
the audio input transducer and the audio output transducer for reducing
RF interference over the predetermined frequency range from the adjacent
mobile wireless communications device. Moreover, the telephone may also
include at least one RF audio input filter element connected to the audio
input transducer and at least one RF audio output filter element
connected to the audio output transducer, both of which are also for
reducing RF interference over the predetermined frequency range from the
adjacent mobile wireless communications device.
