Cellular speakerphone and method of operation thereof

摘要

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).
