Welcome to Poly Community.
Troubleshooting or providing support via the community is outside the scope for myself as an Poly employee.
Please raise a ticket with Poly Technical support.
You will need to provide the following:
• Provide HUB verbose logs (if reproducible)
• Video of issue if possible as it will help visualize the issue.
• -Serial number or firmware version of headset/speaker/USB dongle when issue is noticed.
• Softphone version in use.
• Firmware version of Savi Headset and OS Version of your computer.
