Last Update: August 9th, 2021
There are no direct fax features built into Magic Jack.
According to Magic Jack, connecting a fax machine should work. We caution readers, however, that many VoIP phone services are incompatible with fax machines.
On this page, we’ll give instructions on how to try to connect a fax machine to Magic Jack.
Popular alternatives to faxing through Magic Jack are:
- An online fax service. Some of them combine both phone and fax in the same package.
- A fax machine (or computer with fax software) connected to a landline phone line.
- Printing the fax and sending it from a store with fax services (such as copy/print shops or a library).
Can I send and receive faxes with a fax machine connected to Magic Jack?
According to Magic Jack, “it should work fine.” We’re skeptical (as we are with all fax through VoIP connections).
VoIP services (such as Magic Jack) are known to very incompatible with fax machines. Even when a connection between an internet phone service and a fax machine works, often it is not reliable.
Sending and receiving a fax with Magic Jack (maybe)
We’re cautious about this working. Even when a test fax works, the reliability of the connection is not guaranteed.
What you will need
- A Magic Jack account and phone number
- The required equipment to connect to Magic Jack
- A fax machine (or a computer with a fax modem and fax software)
A computer cannot simply plug into a Magic Jack system and start faxing. It needs to be connected to Magic Jack through the fax modem, and have fax software to send and receive faxes.
Step 1 – make sure Magic Jack is working
Test the Magic Jack connection by connecting a regular telephone to it and placing (and receiving) a phone call.
If the phone is able to place calls through Magic Jack it means that the phone connection is currently working.
Step 2 – connect the fax machine to Magic Jack
Set up the fax machine (or computer with a fax modem and fax software) and connect it to Magic Jack the same way it would connect to a regular telephone line.
Step 3 – try it out
Send a test fax to someone with a fax machine.
Alternatively, we keep a list of services that send and receive test faxes.
Step 4 – adjust settings on the fax machine
If the fax machine is not yet working, we’ll adjust the settings on the machine to make the signal easier to understand through the VoIP service. Not all fax machines will have these options.
- Lower the baud rate on the fax machine as low as it can go. If there is no “baud rate” feature on the fax machine, look for a similar function.
- Turn error correction mode (ECM) to off.
These changes will help the fax signal be better understood as it is transmitted by through the VoIP phone system.
Step 5 – try it again
Repeat Step 3 – test the fax connection.
If the test fax is not working, be sure to return baud rate and ECM to their original settings.
Plugins, apps, and adapters for faxing with Magic Jack
There are none that we’re aware of. Either the fax machine will work while connected to Magic Jack, or it won’t.
