Plantronics TR-11 Adapter (Avaya Partner/Home Use):

Compatible with Avaya Partner Telephones and Home Office – The TR-11 (Formerly TR-1) adapter allows you to answer and hang-up remotely with your wireless headset. Use the TR-11 in-place of the HL10 handset lifter to eliminate the physical lifting of your handset. The TR-11 triggers your hook-switch electronically.


NOTE 1: For use with Plantronics CS500/W700 Series Wireless Headsets Only.

NOTE 2: We strongly discourage using this device for home/residential setups with VoIP phone service.  We continually have compatibility issues and numerous VoIP services have caused constant ringing in the TR-11.

NOTE 3: The TR-11 does not contain a plug for a busy light.  However, purchasing a 3.5 Y-cord from your local electronics store, you can connect a busy light and TR-11 for proper operation.

TECH TIP:Is not compatible with busy lights (3rd party 3.5mm Y-cable required for busy light)
