VTech TL86009 Cordless Telephone User Manual

I subscribe to a nontraditional telephone service that uses my
computer to establish connections, and my telephone does
not 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 provider. Contact your service
provider for more information.
Common cure for electronic equipment:

Wait for the cordless handset to reestablish its connection
with the telephone base. Allow up to one minute for this to
take place.
