Troubleshooting
Appendix
I want to block a cell phone number.
f
If you want to block calls of a cell phone number, add the
number to the block list.
While screening a home call, the telephone suddenly stops
screening and connects to the call.
f
Another handset may have picked up the screening call.
f
If you have another telephone system sharing the same
telephone line, and someone picks up the call on the other
telephone system while the screening is in progress, the
screening process will be terminated and connect you to the
caller.
My telephone block calls from someone I know.
f
You may have saved the caller’s number in your block list. If yes,
remove the number from the list.
I subscribe to a nontraditional telephone service that uses my
computer to establish connections, and my telephone doesn’t
work.
f
Make sure your computer is powered on.
f
Make sure your Internet connection is working properly.
f
Make sure that the software is installed and running for your
nontraditional telephone service.
f
Make sure to plug your USB telephone adapter into a dedicated
USB port on your computer. Do not plug it into a multiple port
USB hub (USB splitter) that is not powered.
f
In a few rare instances, the USB port on your computer may not
have enough power. In these instances, try using a USB hub with
its own external power supply.
f
If you are using a firewall, it may prevent access to your
nontraditional telephone service provider. Contact your service
provider for more information.
