The Plantronics A10 Direct-Connect headset cable is for call centers that use both Plantronics Polaris brand headsets and amplified headset solutions like the M12 or M22 Vista combined with any h-series headset (e.g. H251).
The A10 adapter cable allows for Plantronics standard H-Series headsets (e.g H251 SupraPlus) to be connected to direct-connect telephones (equipped with A10 compatible RJ9 (smaller version of RJ11 modular jack) port).
Flexibility and inventory reduction - agents can be issued one headset as they move between both types of phones.
Amplifier not required.
