Poly MDA220 USB-A Headset Adapter 8A7E0AA

The Poly MDA220 USB-A Headset Adapter is designed for people who want to use a compatible Poly headset across desk-phone and computer calls, with support listed for Blackwire, Voyager, Savi, EncorePro USB, DA Series and BT600 devices.

Recommended For

• Office workers who regularly switch between a compatible desk phone and a PC softphone and want to use one headset for both.
• Organizations moving to unified communications that need to keep existing desk phones in service while adding PC softphone calling.
• Teams using supported Poly USB headsets who need a shared headset setup for calls through Microsoft, Avaya, Cisco, or other compatible softphones and desk phones.
• Desk-based callers who want to answer or end desk-phone calls from the headset, provided they add a compatible EHS cable or HL10 lifter where needed.

Real-World Use Scenarios

• At a desk where both a desk phone and a PC softphone are used, connect one compatible Poly USB headset and select the phone or computer audio button to handle calls without swapping headsets.
• During a gradual move to softphone calling, keep using the existing desk phone while adding PC calls through the same headset; switch audio channels with the MDA220’s buttons.
• When calls arrive on both a desk phone and a supported PC softphone, use the illuminated controls to identify and select the audio channel you need; the adapter helps manage the two sources from one headset.
• In an office that wants to answer or end desk-phone calls from the headset, add a compatible electronic hookswitch cable or handset lifter; remote call control depends on the phone and accessory setup.
• For a workstation using a compatible Poly wireless USB headset, plug its supported USB adapter into the MDA220 to use that headset with desk-phone and PC audio; confirm adapter compatibility before setup.
