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 into a multiple port USB hub (USB splitter) 
that is not powered.
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.
If you are using a firewall, it may prevent access to your nontraditional 
telephone service. Contact your service provider for more information.
Common cure for electronic equipment.
