Even though most things have been standardized, the cord connecting the phone with the handset or headset is anything but, as each telephone manufacturer has its own wiring code. Until now. The Jabra GN1200 universal "smart cord" provides you with a simple solution to connect your Jabra headsets with virtually every telephone that supports a direct connect headset (telephone with dedicated headset port).

Works with virtually all phones with an RJ9 headset jack – including VoIP phones
Microphone amplification boosts transmit levels when connecting to low transmit volume phone systems
Simple slide adjustment for easy setup
Coiled cord for extended range

What do you do when you hook up a new headset and you don't hear a dial tone? The problem could be the headset or the telephone. But chances are it is the cord.

Even though the headset and telephone may be plug-compatible, the wiring is determined by the individual telephone manufacturer.

The Jabra GN1200 features eight separate wire configurations — including three with built-in microphone amplification. Just connect the Jabra GN1200 and headset through the Quick Disconnect plug and adjust the slider from one position to the next until a dial tone is heard. It's as simple as that!
