Below you will find directions for switching the phone number that your computer dials. Please select the appropriate document based on what operating system (and for the Macs, what software) you use to connect to the internet. If you are using a different operating system such as Windows 3.1 or Windows NT and can not find where to change the phone number and DNS on your own, please call us for assistance (805-649-5862). I suggest printing out the instructions so that you can easily reference them if necessary.
