Give users direct control over calls without breaking their workflow. The Poly APS-11 Savi EHS accessory connects compatible Poly Savi wireless headsets to supported Siemens desk phones, enabling electronic hook switch operation for answer, end, and call management from the headset. In busy voice environments, that matters. EHS support reduces the need to touch the handset, helping teams move faster while keeping desks cleaner and equipment handling to a minimum. It is a strong fit for contact centers, front desks, and office teams that depend on Siemens telephony and want a more efficient headset experience. This accessory is built for organizations that value predictable integration over broad claims. When paired with the right Poly and Siemens endpoints, it helps standardize headset workflows across users, improving consistency and reducing friction in day-to-day call handling.
