following:


If your problem is fax-related, check that there are no problems with the fax machine you are calling and that it is
compatible with fax modems.
 For optimum performance, verify that your ISP point of presence (POP) phone number is compliant with V.90
standards.
 If you are having a problem connecting with your ISP, check that they are not experiencing technical problems.

Try connecting your modem through another phone line, if available.
