Incoming Calls Break Net Connection

Solutions:
If you have Call Waiting on the phone line that you're using to access the Net, incoming calls will interrupt your Net connection. Depending on how your connection software responds to such disruption, you might have to reboot your computer as a result. If incoming calls pose a problem for you:

Temporarily disable Call Waiting on your phone line by dialing *70 (some connection software can do this for you automatically). On an office line, dial "9" first. Call Waiting will automatically be restored when you disconnect. Exact procedures may differ by region and phone company; contact your phone company for details.
Switch to a phone line that does not have Call Waiting.
Permanently cancel the Call Waiting service on your phone line.
