Internet Fax services

Sometimes sending something as a fax is preferable to sending it by email--some companies just seem to respond more effectively to a fax than to an email. Or conversely, some senders prefer for whatever reason to send things by fax. Some small businesses may not want to have a fax machine, or a dedicated fax line. Internet fax services allow you to send and receive faxes without having to maintain a fax of your own.

Another advantage of an incoming fax service is that senders never get a busy signal; the service will receive a virtually unlimited number of simultaneous faxes and pass them all on to you. On the outbound side, a service can similarly send out a fax to a number of locations all at once (fax broadcasting), without tying up your fax phone line for hours.

in this case how are you going to send the so called fax.
If you scan a document and email it. I don't think this is called fax.

That's the point of a fax service: you scan the document, upload it to the service (by email or by web), and the service sends it to the recipient's fax machine. You don't have to have a fax machine, though if you want to send a copy of a paper document you have to have a scanner. However, you can also create direct output from your computer (a Word document, for instance) and send it via the service to someone else's fax without ever making a paper copy.

If you send a document from your email to another fax machine that is busy, would the email bounce back?
