Troubleshooting
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. •
