Abstract: A method and apparatus for recording and playing back a sales presentation is disclosed. A telephone interface device is connected to a telephone base, handset and recorder to permit recordation of a sales message using the telephone mouth piece as the recorder microphone. The recorded message has the same sound quality when transmitted over the phone lines as does a normal, live transmission. Transit to and from live and recorded voice is undetected by the party hearing the sales presentation over the phone. Use of the telephone interface device and the recorded sales presentation precludes fatigue and discouragement on the part of the telemarketing sales representative in the face of repeated repetitions of the same sales message and frequent rejections by prospective customers.
