Troubleshooting
System does not receive caller ID when on a call.
•Make sure you subscribe to caller ID with call waiting features from your telephone service provider. Caller ID features work only if both you and the caller are in areas offering caller
ID service, and if both telephone service providers use compatible equipment.
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 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.
