A headset (32) for use with a telephone (24) includes a housing (34), which is configured to be fastened to a head of a user (22), an earphone speaker (38) associated with the housing, and a microphone (40) associated with the housing. An encryption processor (44), contained in the housing, is coupled to receive and encrypt audio input from the microphone so as to generate outgoing encrypted audio data, for decryption using an encryption key that is not available to the telephone. A telephone interface unit (46), contained in the housing, is configured to convey the outgoing encrypted audio data over a link to the telephone for transmission by the telephone over a telephone network, and to receive incoming audio data over the link from the telephone to be played as audio output via the earphone. |
