HP Poly MDA105 Headset PC-Phone Switch – QD Switch, PC + Desk Phone (8A7E2AA)

The Poly MDA105 Headset PC-Phone Switch (8A7E2AA) allows a single QD headset to connect to both a desk phone and a PC, with a one-button switch between the two audio paths. A more advanced version of the MDA100, the MDA105 supports QD headset connectivity for both desk phone and PC audio, making it well-suited to contact centers and enterprise deployments where agents handle both PSTN desk phone calls and softphone/UC calls from the same workstation.
