The short answer
Once you have confirmed, the fax is queued and sent as soon as a line is free. Expect roughly a minute per page for the call itself, plus the time in the queue.
The duration varies with the page count, the quality of the line and the recipient's machine. The how it works page describes each step.
Before the call starts
You open the confirmation link in your email, wait for a short countdown of under a minute, and the fax enters the queue. From there it is sent as soon as a line is available.
No exact delivery time can be promised, since it also depends on how busy the recipient's number is.
During the call
Fax speed is modest, and it is the recipient's machine that sets the pace: an older device negotiates a slower rate. As a rule of thumb, count about a minute per page.
A line in poor condition can slow the call down or interrupt it. The status page shows the progress live, and the result appears as soon as the call ends.
