Connecting a Fax Machine to Ooma

A standard phone splitter (duplex phone splitter) can be used to connect both a phone and a fax machine or DVR to the PHONE port of the Ooma Telo.

When placing fax or modem calls, you must dial *99 before dialing the destination number. Successful transfers mainly depend on the quality of your Internet connection.

Alternatively, you may choose to dedicate the PHONE port usage to only connect a fax machine (or a DVR, for example) and use the cordless Ooma Telo Handsets as phones.

Be sure that the auto-answer mode on the fax is turned off or if turned on the delay to auto-answer should be set very high in order for the Ooma Voicemail to handle unanswered voice calls.

Fax Mode

If you send and receive many faxes, you can enable "Fax Mode" on the Preferences->System page in My Ooma. This enables Ooma to run in an optimized mode for faxing. In this mode, you won't need to dial *99 before you place your fax calls. If you're using an Ooma Telo system, this mode is required to be enabled if you wish to receive faxes on your Ooma Telo.

Note: In fax mode, your calls are sent and received using a different audio codec. In certain conditions, this can cause the quality of your voice calls to diminish. As a result, we recommend that you only enable fax mode only if you're actively sending and receiving faxes.
