Configuring the V.34 setting to Disable (Enable is the default setting) to lower the speed.
Voice over IP (VoIP) services provide normal telephone service, including long distance service through a broadband Internet connection. These services use packets to break up the voice signal on a telephone line and transmit it digitally to the receiver, where the packets are reassembled. The VoIP services are often not compatible with fax machines.
If you continue to have problems faxing, contact your VoIP provider. Because the installation process varies, the VoIP service provider will have to assist in installing the all-in-one fax component.
Although a fax might work on a VoIP network, it can fail when the following events occur:
• Internet traffic becomes heavy and packets are lost.
• Latency (the time it takes for a packet to travel from its point of origin to its point of destination) becomes excessive.
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.
Vonage claims to work with all fax machines. However, some customers
report having had trouble sending and/or receiving faxes with Vonage
and other voice-over IP (VoIP) providers. The difficulties are a
frequent topic in help forums and even made the Wikipedia entry for
Vonage. Frustratingly, the problems have been intermittent and hard to
diagnose, and some customers have resorted to buying a new fax machine
that better-suits Vonage’s optimum specifications. The company’s
official “help” resource suggests lowering the baud rate on the fax
machine to 9600 (or “slow”) as well as disabling the machine’s ECM
(error correction mode) feature, if applicable. Also, make sure the fax
machine is on the “standard” setting. Some users have had good luck
adding *99 before dialing, as that resets the bandwidth for that call. Vonage
also allows its customers to send faxes over the Internet, without a
fax machine, by uploading documents to the Vonage web site. There is no
additional charge for this service if you’re on the company’s
“Unlimited Plan.” Per-minute customers will see fax use applied toward
their monthly minutes allowance. Hope this helps.
Are you connected to a VOIP line for your fax?
A VOIP line can come from a company like Vonage or your local cable co.
Unfortunatly, faxing over VOIP (Internet) is not always successful. You might want to talk to your VOIP provider if they have a solution.
Are you trying with the same fax to send and recieve? Some traditional fax machines have probles connecting to fax modems, which is what you have in an Office Jet.
Try having someone else send you a fax and try sending to another number. Otherwise, you might have a defective fax modem.
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.
I can tell you after trying Vonage a few years ago and them telling us to change all sorts of settings on the machine, that faxing never worked and now I have no idea what the factory default settings should be. So, if you decide to try it, WRITE DOWN THE DEFAULT SETTINGS so you can switch them back if you need to!
