I am using my Blackwire 3200 series headset with RingCentral Phone on my Windows 10 laptop. I have the latest version of Plantronics Hub installed. In Plantronics Hub, in the settings for Ringtone & Volume, Under Software Settings, there is the Ring Location setting. If I set that = All Attached Audio Devices, It causes extra phone ringing AFTER I answer a call or send it to voicemail (using the RingCentral Phone app). I'm pretty sure the extra ringing is NOT related to RingCentral, because the extra ringing uses a completely different ringtone that the one I have for RingCentral.
If I change that setting to in Plantronics Hub to Primary Device Only, there is no such issue.
What's going on?
