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.
