Thanks Gary, although I don't have call waiting, putting in the *70 fixed the problem. The phone now gives a busy signal

Hi
It sounds like you have Call Waiting
You'll need to disable Call waiting, depending on your phone provider it can
be either *70, #70, or something else. Please check with your phone provider
to find out which string disables your Call waiting
To put the settings in, go to your Control Panel -> Phone and Modem Option
and in your Dialing Rules edit Your location profile and you'll see a
checkmark box that is labelled To disable call waiting, dial.
Put a checkmark in that box, and put in the correct string
Now hit OK
