This Jabra GN 1216 cable provides compatibility between any Jabra/GN Netcom headset and an Avaya One-X 9600, 1600 Series IP desktop office telephones. The GN1216 solves the issue with the Avaya special interface which supports sound level protection and works with all of our headsets to properly adjust the volume levels. There are switchable settings for these Avaya phone models for each headset. Cord will only work on above mentioned phones and is not a "universal" solution in applications presently served by the GN1200 or GN1210 cords.
