AT&T EL52200 Quick Start Manual page 23

I hear other calls while using my telephone.
• Disconnect the telephone base from the telephone wall jack, and plug in a different
telephone. If you still hear other calls, the problem is probably in your wiring or
telephone service. Call your telephone service provider (charges may apply).
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.
