1. A portable cellular speakerphone comprising:
- a housing;
a transceiver circuit disposed within said housing;
a processor and switching circuit disposed in said housing and coupled to said transceiver circuit for controlling said transceiver circuit;
a coupler carried on said housing and coupled to said processor and switching circuit for communicating with an optional handset; and
a hands-free user interface disposed within said housing and coupled to said processor and switching circuit, said hands-free user interface including a first microphone and a first speaker for operating the portable cellular speakerphone in a default hands-free mode, said processor and switching circuit coupling said hands-free user interface to said transceiver circuit in a default hands-free mode, and said processor and switching circuit responsive to detecting an activation indication signal from an optional handset coupled to said coupler to automatically interrupt the default hands-free mode to permit the portable cellular speakerphone to operate in a handset mode.

Abstract
A cellular speakerphone (100) includes a housing (101) containing a transceiver circuit (203), a processor and switching circuit (205), a coupler (209), and a hands-free user interface (207). The processor and switching circuit (205) and the hands-free user interface (207) operate the cellular speakerphone (100) in a default hands-free mode that is automatically interruptable to permit the cellular speakerphone (100) to operate in a handset mode when an optional handset (127) is operably coupled to the cellular speakerphone (100) via the coupler (209).
