This is a strange problem you have here my friend. I found the manual if you need it. it is located here: http://www.brother-usa.com/Data/Documentation/Fax/User/UM_FAX575.pdf If you cannot sort it out with the manual, I suggest that you contact Brother USA and see if they can assist you. their telephone number should be on page 1 I think Good Luck

You have to change your OWN ID (fax) number through the menus.

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.

This turned out to be a Vonage issue. I was able to fax from my landline. I googled vonage and mx700 and found a number of similar issues. I also ended up setting my speed to 9600 and turning off TX error reporting. A quick call to vonage and an updated profile (not sure what they did) resolved the issue.

Do you have a DIGITAL phone service like Vonage?

Fax machines are ANALOG devices and will not work reliably on a DIGITAL phone line..

You may not need a separate fax line from Vonage. If you don't need a dedicated fax line, you can try changing the "Bandwidth Saver" settings on your Vonage voice line from your account on the Vonage website. Perform the following:

1. Login to your Vonage account online and click the "Features" tab.
2. Scroll down to the "Bandwidth Saver" link and click on the "Configure" button.
3. You will see a scrollbar with 3 settings: 30kbps, 50kbps and 90kbps

NOTE: My "Saver" was set to 90kbps (Highest Sound Quality) by default.

4. Click on 30kbps (Normal) and click "Submit".
5. Wait about an hour before testing as it could take that long for the change to take effect.
6. Send a test fax to the HP fax test service at 1-888-hpfaxme (1-888-473-2963).

NOTE: This is a GREAT service provided by HP. If your fax goes through correctly, you will receive a return fax within five minutes.

We upgraded to Verizon FiOS and never thought the increased upload speed (4mbps) would present an issue sending faxes. WRONG. We never had fax issues with DSL, Comcast or even Broadstripe VOIP service but for some reason Vonage + FiOS = no fax. That is until we set our Vonage VOIP sound quality to "Normal". Our phone voice quality has been much more reliable since throttling back. This sentiment has also been shared by other Vonage users who have experienced echoing and noise when utilizing the higher quality settings.

Your phone coversations may not have FM quality sound but they will have AM quality and usually that is just fine.

If your fax machine has a Telephone Answering Device (TAD) setting, you can share your voice line with your fax machine and be able to receive faxes and voice messages. Hopefully this will work for you.

It will most likely be more cost effective if you just purchase a new fax machine this is not a high end model.

You can do a web serch type in "parts for sharp fax machine UX105. good luck

set baud rate to 9600 or slow
set resolution to standard
set error correction mode (ECM) off
.
.
if fax has overseas mode turn it on

vonage can make changes to the line that could help, if your using a voice line with call waiting use *70 prior to the number to disable call waiting for that call

Do you have the same problem with different numbers that you fax to? Are you usinga voip phone service? I use Vonage and have a lot of trouble with faxing. Call the number you are faxing to with a different phone and listen for a fax tone.
