This cable is required to connect your phone to your intercom's rear AUX Port in order to make and receive calls. In addition to allowing phone conversations through your intercom, this can also act as your music cable to stream music into your intercom.
When using this specialty cable to stream music, any intercom with VOX will not automatically attenuate the music volume. To continue to experience music volume attenuation with VOX based intercoms, please use #CS-MUSIC connected to your 3.5mm input port.
This cable is only compatible with iPhones, other cell phones and some satellite phones.
