330000008028 Yealink Yealink IP Phone Series Phone Accessory

The Yealink 330000008028 is a Quick Disconnect (QD) to RJ9 adapter cord designed to connect third-party headsets to Yealink IP phones and compatible devices. The cord features a specific pinout configuration (R,M-;M+;R) to ensure proper audio signal routing between the headset and the telephone handset port.

This adapter cord is intended for organisations that wish to use their existing QD-terminated headsets with Yealink desk phones rather than purchasing Yealink-branded headsets. The RJ9 connector plugs into the handset port on the phone, whilst the QD connector attaches to compatible corded headsets from various manufacturers.

QD to RJ9 cords are essential accessories in contact centre and office environments where staff require hands-free communication. The specific pinout designation indicates this cord is configured for particular third-party headset models, so compatibility should be verified before deployment.
