1021 USB Dual Handset Adapter
The 1021 USB Dual Handset Adapter (DHA) allows two people to share a Nortel/Avaya 1100-Series IP Phone so they can join in on the same private conversation with a remote party.
Capable of supporting any combination of two handset or headset devices, features of the USB Dual Handset Adapter include individual volume, muting, and on/off ("exclude") control.
Applications and Benefits
Ideal for training, language translation, and quality monitoring applications, the USB Dual Handset Adapter offers more security and privacy than using a speakerphone. It is also more effective, convenient, and hygienic than sharing a handset or headset.
Note: The 1021 does not include a handset or curly cord.
