The Jabra GN1200 cable is the answer to the widespread problem of not being able to connect the headset and phone. Although most things have been standardized, the cord connecting the desk phone to the handset or headset is far from standardized, as each phone manufacturer has its own code. With the Jabra GN1200 you now get a universal sound processor cable - one practical cable that fits almost any phone. The Jabra GN1200 comes with eight microphone volume settings to ensure that the volume for all outgoing calls is at the same comfortable level.
