What can the Male 2.5mm to Male RJ9 Adapter Cord Work With?

Product Code: PTS/2.5/RJ9/MALE

This cord connects corded or wireless headset systems that have an RJ9 output jack (like the M22, S12 (DISCONTINUED), GN8000MPA (DISCONTINUED), Sennheiser Corded Headset Amplifier, UI760 (DISCONTINUED) and Executive Pro systems) to corded phones via a 2.5mm headset jack.


Common corded phones with 2.5 mm jacks:

AT&T 955 Panasonic KXTS-3282

AT&T 964 Panasonic KXTS-500

AT&T 974 Panasonic KX-T105

AT&T 992 Panasonic KX-TS108

RCA Executive Series Panasonic KX-TS620

Panasonic KX-TS208

Connecting the M22 to your phone’s 2.5mm jack

The male RJ9 jack plugs into your headset amplifier via the jack designated by the diagram of the entire telephone set (both the phone base and handheld receiver – or the abbreviation “TEL” on Executive Pro systems). The male 2.5mm jack plugs into your telephone (Panasonic KXTSC14-B pictured left) into the 2.5mm headset jack.

This connector allows the use of amplified headset systems for additional sound control and lets the user keep their phone on the hook while using a headset. This does not work for cell phones with a 2.5mm headset jack. We also would not recommend this connector for cordless phones at this time.
