Have you tried to figure which cable is compatible with your phone when using a corded Jabra headsets. With more then 20 types of cords the task can be overwhelming. Well stop suffering. The new Intelli-Cord takes the guesswork out of the equation. This cord is designed to work across multiple phones that have modular headset ports (RJ-9/RJ-22) including Cisco Nortel, NEC, Mitel, Toshiba, ShoreTel, Yealink, Polycom. You will also save tons of money if you have many users. Why spend all that money on cables?
Note: This cable will not work with phones that have a round mini 2.5 "pin" port. This cable will NOT work with Avaya 1900/9600 series phones. Example of RJ9/RJ22 headset port below.
