Fax Boxes

A faxbox is a virtual fax machine that enables you to send or receive faxes through email. Having a faxbox means that anyone using a fax machine can send a fax to your faxbox number and you can receive it as an email. Also, you can send paperwork to a fax machine from your faxbox email address.

Alternatively, you can set up a faxbox at Smart PBX > Users > User Features > Faxbox, see Setting up fax to email.

Adding a faxbox

  1. Go to Callflows > Fax Boxes.
  2. Click Add to create a fax box for general use.
  3. From the "Assign to" dropdown, select the generic fax user.


    This automatically names the faxbox and adds the notification email addresses for inbound faxes and fax sent receipts. If necessary, you can change the email addresses at this point.

  4. Go to the Advanced > Caller ID tab and enter the details:

    • Caller ID: the required fax number
    • Caller Name: the organisation or persons name (if it is a personal fax box)
    • Fax header: appears in the header of the fax, leave it as "IP Telecom Fax Printer"
    • Fax identity: repeat caller ID
  5. Save your changes.

  6. Go to the Advanced > SMTP tab and enter the details:

    • SMTP permission list: This controls which user domain can send email-to-fax with an @ prefixing. For more than one domain, add the second with only a space between it and the first. For example ‘@iptelecom @teams’. **For "gmail" do not include the @ prefix, e.g.
  7. Save your changes.

  8. Go to the Advanced > Options tab and enter the details:

    • Retries: leave at 1 for setup; can be customised if required
    • Fax timezone: the timezone where the company is located
  9. After you click Save, go back to the SMTP tab and you will see a new "SMTP email address" field, for example This is the domain that is used to send faxes.
