Yes, it's OK to connect a fax machine to your computer without changing the modem.  The fax machine is independent of your computer and does not use the computer's modem.  The fax machine is strictly and extention of your telephone when it is connected to your phone line.  A computer fax modem is for sending faxes using the computer, not a separate fax machine.

Thank you double that info was greatly appreciated, again thanks

I have a problem with my FAX configuration. Inbound, everything works fine. I can receive a FAX. Outbound traffic is the problem. While dialing, the Modem appears to attach my own phone number to the recipients number! The AT string shows "My Phone Number"+"Recipients Number". I can't find any entry where I could suppress this. Can someone help here? Thx in anticipation.

btw am using Windows XP (Home)
