How a fax gets there
No bounce is not a delivery. A fax is a phone call: mFax dials, the two machines agree on a speed, your pages cross one at a time, and the terminal in the other building confirms every page came through. That confirmation is what you get back — on the row, and as a PDF receipt. And when it doesn’t go through, the row says why.
Dialing, or pages crossing right now.
Their machine confirmed the transmission.
Somebody faxed your number. The PDF is in the app.
Where it runs
Web, iPhone and iPad, Mac, Android, Windows. The same faxes, the same PDFs and the same number on all five — and the web app opens the composer the moment you land on it.
