Not an Outlook problem - suggest you post to a Windows XP group for hardware since this option would be a part of your modem software or a third party program. You can also try Windows Fax group(s).

After furious head scratching, beppe005 asked:

| I have to send faxes via computer, I use winxp, to sume numbers where
| you have to listen a voice and then digit an extension.
| I mean, if I were to use a "normal" fax machine, I dial the number
| and then a voice says for faxes digit "52", for voice message digit
| "53".
| Is there a way to send faxes to those numbers?
| I tried to "join" the phone number to the fax extension number but it
| didn't work.
|
| Someone can help me?
| Thank you in advance.
