PHP form to fax?

I know in the past it wasn't possible to do something like have a user fill out a web form and that information would then be sent to a fax machine. This would require some sort of dialing abilities on the server. Is there anything available today that could perform such a function possibly within PHP? With all the IP telephony abilities, I figured maybe something is available now. I'd like to have the option to send web form information to email or fax. Email isn't a problem but fax I'm kind of stuck. Any ideas? __________________________________ Do you Yahoo!? The New Yahoo! Shopping - with improved product search http://shopping.yahoo.com
