Fax magicjack My magicjack makes calls fine, but when hooked up to my fax machine I keep getting a "busy, no signal" error message.

A voice over Internet protocol device, magicJack allows you to make and receive telephone calls from your computer using a USB device. While magicJack does not officially support sending and receiving faxes, you can connect a regular fax machine to the magicJack device to send and receive faxes.
Attach the magicJack device to a USB port on your computer.
Connect the phone wire to the port at the end of the magicJack device.
Connect the other end of the phone wire to the "Input" jack on your fax machine.
Turn off error correction on your fax machine, and set your fax machine to the lowest possible transmission speed. Consult your fax machine's user guide if you do not know how to turn off the error correction or lower the transmission speed on your fax machine.
Send a fax to your magicJack phone number to receive a fax. You can find your magicJack phone number at the top of the magicJack splash screen that will display on your computer after inserting the magicJack device.
Send a fax from your magicJack by loading the fax you want to send into your fax machine and pressing the "Send" button.

Make sure you have pluuged the telephone line lead into the "LINE" socket and not the "TEL" socket of the fax machine. I reckon thats why you are not dialling out correctly. If this is in an office, make sure you are dialling the access number for an outside line, usually a 9 before the phone number.

Unplug the phone line from the fax machine. Wait at least 1 minute then call the phone number that goes to the fax machine from another line such as a cell phone. Make sure you get a ring and not a busy signal. If you get a ring then hang up the phone. Plug in the fax machine again and call the fax number again. If you get a busy signal then either your phone if off the hook, the switch that is actuated when the phone is placed in the cradle is bad or your modem in the fax machine itself has gone bad. Another thing to try is unplug the fax machines power cord for 30 seconds then plug it back in. I have seen the modems get "locked up" and keep the phone line open. Unplugging will sometimes reset this and get it working again.
Good Luck and Thank You for using Fixya.

The printer will have it's optimum performance when plugged in to an analog signal. MagicJack has digital signal which is very unreliable. Not really recommended to be used as a fax line since transmission signal through it is poor. Remote Fax Error comes up when you have a poor quality of transmission. Also, check if you have assigned it with the correct fax number and a fax name. But I strongly advise you to use analog transmission signal tel line for faxing. Hope I can assist you more on this. If you need more assistance, leave a comment and I'll get back to it. Thanks.

Unplug the phone line from the machine. Wait a few minutes then try calling your fax number from a phone while leaving the phone line disconnected from the machine. If it rings fine from the phone, then re-install the phone line to the fax machine. Try making the call again. If you now get a busy signal then the modem in your fax machine has gone bad and is holding the line open. Make sure when installing the phone line you are placing the cord into the "line" port on the machine and not the phone port.
Good Luck and thank you for using Fixya.

I had the same problem trying to send out faxes out using my Brother MFC 7340. I use a magic jack phone line. Page 106 of the user manual says if sending via VOIP phone line, you should press menu, then 2, 0, 1 to select "Basic (for VOIP) mode. Then press ok. Then press stop/exit. This cuts the modem speed down to 9600 bps and turns ECM off. Then retry to send the fax. I did that and can now send and receive faxes.

Hello. Please make sure your telephone line is plugged into the correct outlet.

Most fax machines typically allow you to plug the line (the cord that goes from the fax machine to the wall jack) and and a telephone (the telephone connects to the fax machine).

In order to fax correctly, you must plug the line into the jack with a block (looks like a 'T') marked on it. Do not plug the line into the jack marked with a phone hand set marked on it.

This shoulds in detail how to connect the line properly. For this printer the line cord must be plugged into the jack labelled "L"

This will show you how to actually send the fax. On your PDF View select page 42.

I called Kodak support and had to upgrade firm software and reset all the settings to reflect whether I had an answering machine (yes) and call waiting (no). Also found it helpful sometimes to dial out using commas after the 1, to keep it from ringing busy.

Fax display screen always reads, "Auto receive". When attempting to fax, the busy light flashes. Busy light stops flashing for 30 seconds, then starts flashing again.
Above is the default settings for the fax.

NGB0 indicates signal error or line condition error.
U need to check the phone line. U can hook any single line phone to the phone line, check for tones without background noise.

unplug the fax from the phone line. call it from you cell.if you hear your phones ringing in the house, plug the fax machine back into the jack. [you should still be on your cell phone] if the line goes dead or stops ringing, there is a short with the fax machine or wire to the jack.if you hear a busy signal without the fax plugged in, unplug everything you have plugged into phone jacks thruout the house. call your # again.if you hear ringing on your cell phone, plug everything back in one at a time.[again while still on your cell phone] if it was one of the phones plugged into a jack, when you plug the shorted phone back into the jack, the line will go dead again. that phone or cord is the problem.
if still rings busy when everything is unplugged, then call your phone company. it can be an inside wire or jack problem, or the problem is outside your home.
hope this helps
