I subscribe to a non-traditional telephone service (for example: magicJack, Skype or Windows Live Call) that uses my computer to establish a connection, and my phone is not working correctly.

You need to have a high speed internet connection; for example, broadband, cable, DSL, Wireless, Wi-Fi, WiMax or FiOS.

Make sure your internet connection is working properly. In most cases, to make and receive calls, your computer must be powered on.

Make sure the software is installed and running for your non-traditional telephone service.

Make sure to plug your USB telephone adapter directly into a dedicated USB port on your computer. Do not plug it into a multi-port USB hub (or splitter) unless it is a powered hub.

In rare instances, the USB port on your computer may not have enough power; in which case, try using a powered USB hub.

If you are using a firewall, it may prevent access to your non-traditional telephone service provider. Contact your service provider or manufacturer of your firewall for technical support.
