For many organizations, the fax machine remains an integral part of the communications tool set. ShoreTel Sky has solutions to accommodate and enhance traditional faxing.

Supported Configurations

Inbound ShoreTel Sky Fax with Outbound Physical Fax Machine

This hybrid solution is very green and saves money on fax toner and paper.

All inbound faxes are sent to an email address, public folder, or distribution list in your email system. You can then print the PDF file that is emailed to you if you need to use it for sending an outbound fax. The people faxing to you will not experience any changes in processing faxes.

All outbound faxes will be sent using your physical fax machine connected to a "POTS" line.

Pure ShoreTel Sky Fax

Pure ShoreTel Sky Fax is an email-to-fax service used for all of your inbound and outbound faxes. This generally requires the use of a scanner to convert a printed hard copy when the document you want to fax is not saved on your computer or is not a document type supported with ShoreTel Sky Fax. Just print the desired document, use a scanner to save the scanned file to your computer, and add the file as an attachment to an email. For more information, see our ShoreTel Sky Fax article.

Inbound Forward to POTS, Outbound via POTS

If you want to maintain use of your physical fax machine, we recommend that you have a "POTS" line for the fax machine. ShoreTel Sky can "port" the fax number and then permanently forward it to the "POTS" line.

Unsupported Configuration

ShoreTel Sky does NOT recommend or support faxing via ATA's due to the unpredictable nature of the T38 fax protocol and because ShoreTel Sky does not support T38 protocol entirely throughout all of our carriers.


Q: What fax solutions are available?
A: Please see the list of Supported Configurations listed above.

Q: Can I use my current fax machine?
A: Yes. You will need your fax machine if you choose the stand-alone POTS line option. The "ShoreTel Sky Fax (email-to-fax)" service eliminates the need for a fax machine, but a scanner is required to scan and fax hardcopy documents if no fax machine is on premises.

Q: Who will configure and install my fax solution?
A: The ShoreTel Sky team will configure the "ShoreTel Sky Fax (email-to-fax)" service. If not already installed, you will need to install your own fax machine. The stand-alone POTS line is installed by your local telephone provider. 

Q: What type of support is available for my fax solution?
A: ShoreTel Sky does not provide support for the stand-alone POTS line or fax machine, but it does provide full-service support for "ShoreTel Sky Fax (email-to-fax)." Both phone support and on-site support is included with ShoreTel Sky's Outsourced IP Phone System. Most fax issues can be remotely resolved by our support team.

Q: Which fax solution does ShoreTel Sky recommend?
A: ShoreTel Sky recommends the "ShoreTel Sky Fax (email-to-fax)" service for each employee who receives faxes, along with a fax machine connected to a stand-alone POTS line for faxing hardcopy documents.

Q: Can I keep my fax number?
A: Yes. All fax solutions allow you to "port" your current fax number to ShoreTel Sky.
