Windows XP fax issue

Hello.

We want to send a lot of faxes using Windows XP fax service. We do not want to send them one by one but we want to import the fax numbers and then XP fax will send them one after the other in a row.

How can I import the fax numbers into the Windows XP fax?

Do you know a guide that explains how to send a lot of faxes using Windows XP fax service?
