Troubleshooting
I subscribe to a nontraditional telephone service that uses my
computer to establish connections, and my telephone doesn't work.
• Make sure your computer is powered on.
• Make sure your Internet connection is working properly.
• Make sure that the software is installed and running for your
nontraditional telephone service.
• 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.
• In a few rare cases, 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.
• If you are using a firewall, it may prevent access to your
nontraditional telephone service. Contact your service provider

for more information.
