Some optional features include adding a cover page to your fax, adding a billing code, and selecting legal-sized paper. You can even edit the "From" field if you wish to change the name that will be displayed when the fax is received. A cover page allows you to tell your recipient what kind of fax he/she is receiving, for example is it urgent, a reply, or simply a comment.

The best thing about web fax is that it is portable. You can carry your fully-equipped laptop and enjoy fax facility wherever you are. You just need to keep all the information in your laptop and a wireless Internet connection to use this service.
