I recently updated the RingCentral app on my Windows 10 desktop. Since the update, all lines (direct dial and main number) in the office (14 lines) ring on my phone. Also, if I answer a call on my Plantronics headset, I can not transfer calls to another extension. I have to put the call on hold, pick up the call from the handheld and then transfer. I am the person all calls funnel through when they dial the main number. This is a very irritating.
