Hi there

check where your phone cale goes into the machine you will proberbly find two sockets one marked phone and one marked line the phone line needs to go into the one marked line and a phone handset in the one marked phone if this is correct try ringing yor line that the fax is plugged into see if you get a ring or engaged tone if you are getting engaged unplug the fax and try again if this now works the chance is that the modem board in your fax has failed and will require replaceing

Hi irwinbadin,

HP fax products are designed so that other telephone equipment can be connected on the same line as the fax. The unit must be connected first using a two-conductor fax/phone cable like the one that shipped with the HP product. Using a four-conductor telephone cable may cause problems receiving faxes or calls.

There are two different types of phone cables. There are two-conductor phone cables like what originally shipped with the HP fax product and there are four-conductor cables. HP fax products are designed to work with a two-conductor phone cable. Look at the end of the cable and verify that it has only two copper leads or wires. Replace any four-conductor cables with a two-conductor cable. Only two-conductor phone cables should be used to connect the all-in-one to the phone line.

Figure 1: The difference between a two-conductor phone cable and a four-conductor phone cable

Step one: Connect the phone line to the fax
The fax will have two or three sockets (or jacks) for phone lines. Some of these may have a removable plastic plug in them. These sockets will be labeled with text, To Wall Jack , or with a graphic of the wall jack. See Figure 1 below.

Plug the two-conductor telephone cable that came with the HP product into the telephone wall jack. Then, plug it into this socket as shown below.

In areas with above ground telephone lines and electrical storms (lightning), it is a good idea to purchase a telephone line surge suppressor and connect it between the telephone wall jack and the fax. This will help prevent damage to the fax from a lightning-caused power surge on the phone line.

Step two: Add other phone-line devices
To connect other telephone devices, use the other socket (or sockets) on the fax. These are identified by text or with a graphic of a telephone and/or computer.

Connect a caller ID unit between the fax and the telephone.
Use the information below that matches the devices you need to connect.

Fax and telephone
Connect a single-line telephone to one of the added sockets on the fax. The telephone will share the same phone line as the fax. See the illustration below.

Fax, answering machine, and telephone
When a telephone answering machine and telephone are connected, connect the answering machine to the fax and then connect the telephone to the answering machine as shown below.

Fax and computer modem
To use a fax and a computer modem on the same phone line, connect the fax to the computer modem. The modem socket on the computer may be labeled Line or Wall jack .

Fax, computer modem, and telephone
To use a computer modem and a telephone with the fax, connect the computer modem to the fax. Then, connect the telephone into the second phone line connector on the computer modem or the third fax socket (if it is available). The image below shows how to connect a computer and a telephone to a fax with two sockets.

Fax, modem, answering machine, and telephone
The image below shows how to connect a computer modem, answering machine, and telephone to a fax. Connect the computer modem to the fax, then connect the answering machine to the computer, and finally, connect the telephone to the answering machine.
If the fax has three phone line sockets instead of two, some of the devices can be connected to the other phone socket on the fax.

Fax problem


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.

Hi check the following article to from HP

HP FAX ISSUES


Check the TELEPHONE LINE

Make sure that you have plugged the phone cord directly and securely into the wall jack and into the back port of the fax product. The fax port on your product is marked "Line," "To Wall Jack," or with a wall jack symbol.

Check LIU

Make sure the Line Interface Unit (box that the phone cord plugs into) is fully seated into the back of the fax product.

Remove the SPLITTER

Remove any other devices from the line such as splitters, credit card machines, or telephone answering machines.


Can try sending the Fax on Another Line


CHECK WITH DIFFERENT CABLE
Try using a different telephone cord.

Your fax machine is not getting a dial-tone.

Plug a regular phone into the wall jack and listen for a dial-tone
Make sure the phone line is hooked into the LINE port of your fax machine.
Unplug the power cord for 10 seconds.

Problem faxing


Unplug the fax at the wall jack and hook up a regular phone. Listen to the dial tone. It should sound like a regular dial tone.

Next, plug the fax back in and call the machine from a regular phone.

You should hear fax tones.

Problem with fax


Check your phone lines. You should have one that runs directly from the wall jack to the "L" port on the machine (there should be no other devices connected between the wall and the machine). If you have other devices connected (telephone, answering machine, computer modem, etc) they should be connected to the port on the machine that has an icon next to it that looks like a telephone.

Panasonic KX-FM220 fax machine does have a dial tone


I would double check your phone cord. There is usually 2 jacks in the back of the fax machine. 1 is for Line, and 1 is for phone.
Your phone cord should be hooked up in the LINE jack that goes to the wall.
I would also double check your phone cord on another phone to make sure the cord is good.
If you look at the clear connector that you plug into your wall and fax machine, does it have 4 copper/gold color wires contacts imbedded in the clear plastic connector?

Another thing to try, if you fax machine has a Line and a Phone connector, try plugging in a phone in the PHONE connector. Then hook up another phone cord going from the LINE to the WALL jack.
If you get a dial tone on your Phone, then you know you have it connected correctly. If no dial tone, then I would go back to the phone cord.
check those things and get back to me and I will see if I can help you with more suggestions.
Good luck.
Mac =)
