The PH35-RJ9Cisco adapter converts the standard smartphone headset single 3.5mm plug to a standard RJ9, RJ10, or RJ22 handset plug, allowing you to use your favorite headset with your Cisco IP phone. This adapter is designed for use with headsets that have one 3.5 mm plug. The adapter outputs binaural sound for stereo headsets, meaning you will hear sound out of both ears.
The adapter cable is approximately five inches long.
*Only compatible with Cisco and Ativa phones. Does NOT work with Polycom, Aastra, Nortel, and most other phones.
**For optimal use, please plug into the headset jack on your phone. The handset jack usually causes audio distortion
