A telephone docking station that combines the operation of a wireless telephone, a cordless telephone, and a land-line telephone interface is taught. The wireless telephone and land-line interface provide telephone resources to the cordless telephone, which functions as a telephone terminal unit. Telephone calls can originate or terminate from either telephone resource. The cordless telephone handset provides for selection and display of the presently connected telephone resource. Caller ID information from both resources are routed to the cordless telephone. The cordless telephone automatically answers the presently ringing resource when is received. A speakerphone and an answering machine are added as alternative telephone terminal units in an illustrative embodiment. A Caller ID preview and hold function is provided so that the user can manage multiple calls from the telephone resources.
