About Fax Line Index
Online fax services compared on what their own pricing pages print: the monthly price, the pages it includes, the overage, and whether HIPAA is stated with a BAA
What is on this site
6 guides, each with its sources on the page , 58 answers to the questions around them , and the comparison.
- What is a fax number: A fax number is an ordinary telephone number, local or toll-free, that terminates on fax equipment rather than a handset.
- How to send a fax via email: You cannot email a fax number, because a fax number is a telephone number and email travels over the internet, so an email addressed to a fax number goes nowhere.
- How to send a fax without a fax machine: Nobody needs a fax machine to send a fax any more, and most people who need to send one have never owned one.
- Free fax cover sheet: A fax cover sheet is the first page of a fax: who it is from, who it is for, how many pages follow, and a line about what to do if it reached the wrong machine.
- How long does a fax take to send: A fax is a telephone call, so it takes as long as the call: a handshake of a few seconds, then roughly a minute per page on a clear line at standard resolution, longer for dense pages of small text or images, and a retry if the receiving line is busy or drops.
- Fax number porting: Porting is moving a fax number from one carrier or service to another so that clients who have it on file keep reaching you.
