Headset Buddy 2.5mm Headset to Phone Adapter - 2.5mm to RJ9/RJ10 (PH25-RJ9Cisco) Compatible for Cisco phones

The PH25-RJ9Cisco converts the standard phone headset 2.5mm plug to a standard RJ9, RJ10, or RJ22 Cisco phone headset plug, allowing you to use your favorite phone headset with your Cisco office phone. The adapter outputs binaural sound for stereo headsets, meaning you will hear sound out of both ears.

Why buy an expensive headset just for your Cisco IP phone?

Use the Headset Buddy Adapter and your existing 2.5mm phone headset with Cisco VOIP phones that have a headset jack. Save money by using a 2.5mm headset with your Cisco office phone.

The adapter cable is approximately five inches long.

Compatibilty

Only compatible with Cisco and Ativa phones. Will not work with Polycom, Aastra, Nortel, and most other phones.

Will not work with Cisco handset plug or RJ11 (wall) jacks.

This list is not all inclusive. Please look up the specifications on your specific phone to see if it has a RJ9, RJ10, or RJ22 headset jack. If the Headset Buddy doesn't work with a model on this list we will be happy to refund 100% of your purchase plus pay for return shipping
