In the past we've experienced something similar, but not quite the same. Occasionally we'll get that digitized/robotic sound and when we do, all we have to do place the call on hold for a second and pick it back up and that usually resolves the issue.
Additionally, all of us just installed the Plantronics Hub software and updated the firmware on our headsets. We have not had the issue since - whether that's a coincidence or not, I'm not sure.
Hope that helps,
more info to add.
best call quality is from a plantronics savi headset to another savi headset. this is crystal clear.
next in quality is plantronics to a cell phone.
worst is from plantronics to a generic usb headset or to a ringcentral desk phone.
i don't know if the problem is with windows 10, the plantronics headset or ringcentral, or a combination of any of these three.
If the issue is the same without the headset then it would mean there is an issue either with software on the PC or settings on the local network. If you do not get reports of distortion without the headset you may have to adjust the audio settings for the headset in the Plantronics hub software, or Plantronics support may have some suggestions to resolve the issue.
Let us know if this helps or you make any progress.
We recently rolled out RingCentral to our office of 200 users. I
really like there service, but I too have the Robotic voice with my Savi 745
headset using the RC Desktop client. The issue does not occur on every call,
but it does seem to happen to the same numbers (to both internal RC and
external non-RC phones). It appears to be specific to my PC. When I moved my
Savi headset to another laptop it did not have the issue. Both computers are
running the latest 9.3.5 RC Desktop software on the same Windows 10 OS version.
On the computer with the problem, I have found that unplugging and reconnecting the USB port during an active call fixes the Robotic voice issue 100% of the time. However, once that call ends I may need to redo that on the next active call. For callers I know I've spoken to with the issue, I have unplugged the USB and reconnected the USB, after initiating the call but before they have answered, so that active call will be clear.
The Robotic issue never occurs when using the Savi 745 DECT to my VVX411 desk phone. I'm still looking for a permanent solution. I have borrowed a Savi 745 from one coworker that does not have the issue and using his Savi with my PC we had the issue. Moving my Savi to his PC, we did not have the issue. The computers are different models. Hopefully this gives RC support more information to find a solution.
UPDATE: I tried using the hold mentioned above, that did not work for me. I tried turning the 'Plantronics headset' off/on in RC Desktop Settings > Sound, and that worked for the active call, just like the USB method I mentioned above. The Plantronics headset off/on is faster if you already have the settings page opened.
