Poly Lens has/will be replacing the Plantronics Hub currently available in PMPC. The App allows you to upgrade Headset firmware and change Headset settings, etc.
Poly Lens is available from here (https://www.poly.com/gb/en/products/services/cloud/poly-lens/app
) and is a MSI Installer.
It would be great to have this available as both a PMPC App and Updates.
