I want to make sure I understand this completely. You get no dial tone from the fax machine when hooked up to VOIP. In the past, was there an audible dial tone from the fax, or did it just dial silently and give you an error if there was no tone?
When you said you got a dial tone by connecting a phone to the ext phone port of "the machine" did you mean the fax machine? If you get a dial tone by running a phone through the fax machine, then the line is good. I have used a fax machine over Sunrocket before they went defunct, which used the same technology base as Vonage - so it should work.
If you used to get an audible dial tone when using the fax, and no longer do, and you are geting a dial tone on a regular phone that is connected to the ext. port of the fax machine, then the problem has to be in the fax machine itself, not the VOIP.
If you can verify that, we can go from there.
first check the phone line it self. take all phone lines out of the credit card machine, and unplug the power to machine. now take a telephone with a phone line attached and plug that into wall as if you were making a call on that phone. check for dial tone. if you have a dial tone, make a call. do you require a 8 or 9 to dial out? you terminal may not recognize that.
also if you do have dial tone do you use digital or analog phone lines? you need analog for terminals. if you have a fax line you can connect the terminal to fax via phone line. if this does not work contact phone co and ask what type of lines you have, you can also connect most terminals via Ethernet.
First, try to check every telephone line is properly plugged into its phone jack. If you have a problem with just one phone, plug a different phone into that jack. If the second phone works, the problem lies in the first phone.
Then unplug each phone and answering machine in your house, one at a time. Wait 30 seconds after unplugging the first device. Pick up another phone to see if there's a dial tone -- if there is, then the first phone may be faulty. If not, continue unplugging phones in the same way and check for dial tone. If you find a phone that doesn't work, plug all your other phones back in and see if they work properly. The faulty phone should be replaced.
or disconnect the plug from the test jack inside the exterior box. This disconnects your inside wiring from phone company's line. If you have more than one line, select the test jack for the line that is causing the problem. Plug your phone into the jack; this plugs you directly into the phone company's line. If you have a cable modem, plug the phone directly into the jack on the modem.
Then pick up the phone receiver to see if there's a dial tone. If there's no dial tone, the problem is with your outside wiring. If there is a dial tone, the trouble is caused by your inside wiring, equipment or jacks.
There is a
problem either with the Line Interface Unit (LIU, also known as the
fax/phone line connector) or the fax hardware, because the unit is
having problems sending or receiving faxes. The unit may hang on
"Initializing." This document explains how to troubleshoot the LIU and
Please perform the following:
Front panel hangs on "Initializing"
Pull the power cord connector from the back of the base unit to recover from the error.
Unplug the LIU from the back of the
ADF. It is located on the left side (facing it), and is where you plug
in the telephone lines.
Plug the power cord back in, power it up, and see if it hangs without the LIU inserted.
If it does not hang without the LIU
inserted, power the unit down, plug the LIU back in, and power it back
up. If it hangs, the LIU is faulty.
If it does hang without the LIU attached, unplug the ADF from the base and see if it hangs. If it does, the base is faulty.
Testing the LIU
The primary test for the LIU is whether or
not you get a dial tone. Sometimes, you need to re-seat the phone line
several times to get a good connection. If after trying the things
below, there is still no dial tone, or initialization hangs, the LIU may
need to be replaced.
Verify that the phone line is connected directly from the wall jack to the plug in the LIU that says "To Wall Jack."
Verify that the LIU is plugged
securely into the product. If it is not, there will be a message at
power-up saying the LIU is not connected. If it is, the date and time
If the LIU was re-seated, cycle the power on the unit. The unit should display the date and time.
Unplug all other accessories, like a
telephone answering machine or modem. If the LIU appears to work fine
after unplugging them, these accessories may be interfering.
Place a document in the Automatic Document Feeder (ADF). The display will flash "Document Loaded."
Press Start Fax to verify there is a dial tone. If so, try sending a fax.
If there is not a dial tone, unplug
the product from the wall jack, and plug in a regular telephone to
verify there is a dial tone at the wall jack.
If there is no dial tone on the telephone, the wall jack or phone line may be faulty
If you are not getting a dial tone then something is holding the line off hook. Disconnect any other device you have on your lines and check to see if you get your dial tone back. If you still have no dial tone unplug each phone and check again. You may have to disconnect everything for a minute or two so the phone company will reset its equipment. Plug in your phones one at a time and check your dial tone every time you add something new.
If you add something and you loose your dial tone immediately you may have a crossed connection in the wall socket, any splitters or in the phone plug. Check to make sure all of the wires in those sockets are straight before you plug in your phone wire.
If you add your CC machine and everything is good but it fails after you run a transaction you will have to contact the supplier of your CC machine. It is not hanging up the line.
Go to menu option and choose the option fax and set the parameter like auto receive or manual set the ring auto answer mode after certain ring. If it is in auto receiving mode it will receive the fax after the ring which you set. Make sure the phone wire which you insert in fax machine getting proper dial tone and getting out going calling facility. Have a nice day and do not forget to rate please...! Hope this helps. Please rate my response. Thanks.
If the dial tone is not heard check the volume. It may have accidentally been muted or turned down.
Is the phone line plugged into a surge protector? The surge protector
may have stopped working or blown a surge, a sudden burst of
electricity, which may have caused the dial tone in your cordless phone
to go. Unplug the phone line from the surge protector then plug it back
in and see if you get a dial tone? It could be that the phone line
plugged into the surge was loose.
Try a different phone plug, outlet.
If the other phones on that line work OK, disconnect all the phones connected to the line, leave them all disconnected for 3 minutes, and then connect one at a time.
If still a problem and the other phones on that line work OK, give this a try:
Unplug the battery in the handset, unplug the phone line from the base and unplug the electricity from the base. Leave everything unplugged for an hour or two. That way you can get more of an idea of whether your phone will work. After an hour or two, plug in everything.
