Error: Some voice features aren't available right now

Issue symptoms I can make and receive calls but this error appears: Some voice features aren’t available right now. You can still make and receive calls, and multiple features in voice don't work as expected:
The call generates a ticket, but that ticket doesn't pop up automatically in the Agent Workspace
If wrap-up is active, I get dropped from the call
The pause and transfer buttons aren't visible in the call console
Even if the option: Allow agents to control call recording is turned on in Admin Center, the recording control button isn't visible in the call console
When I receive this error, voice encounters poor network conditions and operates in an unstable network mode. This mode prioritizes only essential call functions, so that you can continue to take calls from customers. Once network conditions improve, Unstable Network Mode automatically disengages and full call functionality resumes. If you encounter this error often: Unstable Network Mode, your browser or computer may not be able to connect to the required Zendesk voice URLs. If you don’t allow this communication, you can only accept and decline calls or hang up. Resolution steps To resolve this issue:
Inform an admin that they can enable communication with your computer or browser. If your company already permits all AWS IP ranges, you don't need to add the required URLs for voice. If you add the required URLs or their IP ranges to your company network configuration, ensure that your VPN, firewall, and any antivirus software allow the connections.

Refresh your browser tab. The error message may appear due to poor internet connectivity.
If you open multiple browser tabs when you accept or make voice calls, reduce them to fewer than four to see if that reduces the frequency of the issue.
