Guide: How to send a vFax


Shorthand for “virtual fax,” vFax is a modern fax solution that allows businesses to send, receive, and view fax messages virtually rather than using a traditional fax machine line.

Broken into two sections below, we’ve included steps on how easy it is to use the DOTVOX fax over IP service from both the user portal and a business email address.


vFax from the portal

  1. Visit and log in to the system using your DOTVOX fax credentials.
  2. From the dashboard, click the SEND A FAX icon.
  3. Enter the destination fax number manually or choose from a saved fax address. You may also customize the subject line, cover page, tracking key, sender address, notes, and more directly from this page. Once completed, hit NEXT.
  4. From here, upload up to 10 saved files. Accepted file formats are image files (TIFF, GIF, PNG, JPEG); Adobe Acrobat files (PDF); Microsoft Office files (DOC, XLS, PPT); printer file formats (PCL, EPS, PS); text files (TXT, RTF, XML); and fax cover page formats (FXC). After that, hit NEXT.
  5. Preview your fax message for errors and formatting, then click NEXT.
  6. Choose additional email recipients if needed. Once completed, hit SEND.


vFax from an email address

  1. Log into the primary email account associated with the DOTVOX fax line account. If you need to check which primary email address goes to which fax line, log into the DOTVOX fax portal, click on SETTINGS, and find the primary email address there.
  2. Compose a new email. Address the email to the target fax number (starting with the number 1) For example, a fax intended for 8442834900 would look like:
  3. Attach up to 10 files to the email and/or write a message in the body of the email as well.
  4. Click SEND. The fax is now complete.
