Hi, I work with webex version 41.11.0.20606 and Plantronics Voyager Focus UC with BT600 bluetooth adapter on Windows 10.From 1 month I have this issue. Bluetooth adapter blinks continuously like when I am in calling.If I quit Webex it stop.In earbuds...

I have a ATA 186. When I receive a call the telephone doesn't show the number. The ATA have SIP firmware.Why?
