Usb-a std vers on win10 takes webex and teams about 4 minutes to connect with device connected, but instant without. not using hub. any ideas?

Hi Geronimo, in this case we would need to review your complete setup to find where the issue is coming from. As a first step we would suggest you to test one soft phone at a time, making sure the other one is not running in the background. If possible try uninstalling one, like Webex for example. Review the soft phone versions you have for Webex and Teams. Test the computer with a different USB device and see if you still get the same issue on Webex and Teams. For further assistance, please contact our Customer Care Team at: 800-985-9815.

Can I connect two phones using bluetooth?

Yes, you can connect devices including a phone or a computer via Bluetooth.

I am unable to adjust the volume in small increments - it goes from 0 to 24 for example. Is this a limitation of the speaker or a compatibility issue?

Hi! This is most likely a compatibility issue with the software used. The speakerphone is indeed capable of small-volume increments. We suggest verifying full compatibility by accessing our Softphone compatibility matrix on our Poly Site. Something else we can try is testing on another computer if possible, or reinstalling drivers via device manager and restarting the PC. If you have any additional concerns, please do not hesitate to let us know by contacting our Customer Care Team at 800-985-9815.

I'm hearing sound while mute/unmute, i did turn off that in poly lens, is that sound heard by people in call?

You can choose between three different options to customize the Mute alert whenever you press the button. You should be able to choose between double tone, single tone and a voice prompt. These alerts cannot be heard by people on the other end.
