What is a fax extension?

A fax extension is no different than any other phone number extension. With a fax extension, you share your fax number with others, but you have your own extension that you can use to send and receive faxes.

Your new free fax number consists of FaxExtension general number and an extension, divided by the # sign (like +13473541750#4444). To this number, you can receive faxes as to any other fax number without extension. And you can also send faxes from this fax number extension as from any online fax or fax machine.
