Various methods for using external audio devices with a single mobile telephone are proposed, where the external audio devices have audio input functionality and audio output functionality. To support conferencing, audio data of a single telephone call involving the mobile telephone is communicated with two or more external audio devices. To support separate telephone calls that are concurrent for at least a period of time, audio data of a first telephone call involving the mobile telephone is communicated with one or more first external audio devices, and audio data of a second telephone call involving the mobile telephone is communicated with one or more second external audio devices. If there are two or more first external audio devices, then the first telephone call is a conference call.
