The Jabra GN1200 smart cord with RJ9 connector is the solution to a common problem of not being able to connect your headset and telephone. Even though most things have been standardised, the cord connecting the phone with the handset or headset is anything but standard as each telephone manufacturer has its own wiring code. The universal Jabra GN1200 Smart cord will work with virtually any desk phone with Jabras Quick Disconnect (QD) corded headsets.
