Does cloudUC support any Poly desk phones that will work over WiFi?

Yes! Polycom VVX x50 series phones can be equipped with an optional Obi WiFi USB module to allow the phone to work wirelessly. Note that if the Obi WiFi module is used, the phone still requires power thus a PoE power supply/injector would be required. When equipped with WIFi, the phone cannot act as an access point, it will only support functioning as a wireless client.
