The internal or auxiliary ring detector detects the telephone
ringer and sends a ring tone to the headset earpiece.

speaker, the internal ring detector will recognize when the
phone rings. However, if your corded phone speaker is located
elsewhere on the phone, stick the auxiliary ring detector to the
speaker as shown below.
