Fax doesnt send or recieve

Check that the memory is not full. Also, make sure a setting like (auto-dial 9 for outside line) is set incorrectly.

Is there a dial tone if you pick up the reciever ? Can you send faxes or use the machine to make a phone call ? If you can make calls or send faxes the machine probably needs to be set to the auto recieve mode so that it automatically answers when a fax is being recieved. If no dial tone you may have a loose connection to your phone jack.

the number is busy. Try pressing the monitor button and listening for a dial tone. No dial tone means your phone line is not working. If you have dial tone, dial the number you wish to fax and listen to see if it picks up. If you get a busy signal, or hear someone answer, that is why it's not working. If you hear the fax tones, press start and send your document. This is a way to fax that allows you to hear the whole process.

Have you set for the proper dialing? there's a choice for pulse or tone dialing, you probably need tone dialing. Also the number needs to be put in just as you would dial on a phone.

Plug a phone in to fax port, Is there a dial tone there also? can you dial a number and make a call from the fax port? You should be able to with a regular phone. If you can't, try plugging in the fax machine to the other port where your phone is plugged in. try sending a fax.If it works there, then the Vonage device or your service itself is the problem.

press the "on hook" dial key. this should let you hear a dial tone. If you don't hear a dial tone, then it is probably the phone line and not the machine. You may have to call your telephone company.

Are you plugged into the LINE port?

First make sure that the fax button has been pushed and is llit...

The 2820 should have a handset. In order to use manual transmission (when you get to hear all the beeps and whistles) you will need to load the document then pick up the handset. then dial the number, when you hear the recieving fax tone then hit the start button.

The 2820 should also have a hook hold button pressing this will allow you to hear the dial tone and the numbers you dial along with the receiving fax tone. If you dont hear anything when you press this button then you may want to use the volume buttons to increase the volume.

Also remember that if you have not picked up the handset or pressed he hook/hold button the unit will use automatic mode, which is to say that all you will do is load the document, dial the number, and then press the start button.

Did you plug a phone into the phone jack and see if there is a dial tone?
Thats the first place to start.
After that let me know, and I will give you more ideas.
Sounds like a phone line issue

go into menu
go to fax settings
find send
click auto not manual, please make sure that when you push the hook key you hear a dial tone. always reminder that every fax machine has the capablitiy of either dial or tone. now if everything is set up properly  the problem will be in the tx portion of the board. if you can link up with somebody close to you and try to transmit back and fourth that will let you know if it is their problem or your. it may not be your problem.
