Fax over VOIP? I Can Send Ok, But Can't Receive!

Hi

I have read loads of articles about faxing over voip most of which say it cannot be done, I originally tried faxing through a brother all in-one printer/fax scanner machine and had no luck at all.

After giving in to the possibility it might not be possible I decided to see if i could find some software to run on a PC, all i can find is software that uses a modem, so thinking i could plug my pc in, through the ATA (voip device) I tried it and bingo i could send a fax fine over voip, no problems at all, however when dialing in/recieving a fax, the PC seems to answer the call and then nothing, game over... is there anything i can do?

I have set the codec on the ATA device to G.711 as recommended, i've set all the volume features to there highest. But somewhere things are going wrong...

any help would be appreciated

many thanks

James

SOURCE: Fax problem

If the wall jack has a dial tone, disconnect the telephone line from the telephone and connect it to the jack on the FAX/MFC labeled LINE. Make sure the line cord is connected from the jack on the FAX/MFC labeled LINE directly to the wall jack. Press the Hook or Speaker Phone key or pick up the external telephone handset and listen for a dial tone.If there is still no dial tone, your machine may require service.

Get a new phone wire. Put a phone on the line and listen for static. Too many phones on one line will cause problems. If the phone line is going thru a surge protector, check the quality of the sound with it and without it, it may be damaged. Keep power wires away from phone wires, they cause static.

Fax machine does not receive FAX


The problem is that the codecs used by VoIP IADs are designed to compress voice, not the analog signals sent and received by modems.
In a VoIP Internet world, voice is first converted into packets and then they are sent over the connections that make up our our vast Internet. They may take slightly different times to arrive at their destination. In doing so some packets may be discarded, but the end result is that the receiving VoIP device has enough packets to make a clear and understandable conversation.
We suggest these settings on a fax machine for faxing over VoIP; slowing the transmission rate down and allowing the machine to continue receiving the transmission even though a few bits of data were lost, then faxing over VoIP can become more consistent. Our suggestions in many cases can resolve issues that prevent faxing over a VoIP connection, but not in all cases. If after trying and making all the VoIP fax changes we suggest you still cannot fax over your connection then try a Internet Fax service.

Can dial out and receive incoming calls but will


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.

If so:

Unfortunatly, faxing over VOIP (Internet) is not always successful. You might want to talk to your VOIP provider if they have a solution.

If not:

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.

Cannot send or receive faxes


How to dial *xx codes when faxing When sending a fax, it may be necessary to enter in a *xx code as the first part of the number. Follow the steps below to dial *99 when using a VoIP service. NOTE: Since the *xx code is an instruction to the phone system, this must be dialed live.
  1. To pick up the line on the HP All-in-One, press Start Black Fax or Start Color Fax without entering a phone number first.
  2. When you hear the dial tone, enter in the *99 code.
  3. Wait a few seconds and then enter in the rest of the number.
  4. The HP All-in-One will complete the fax as normal.
What can be done to help the fax transmission? The communication speed is a major factor in fax transmission over VoIP. Currently there are three speed standards.
  • Fast - v.34 which communicates at 33.6 Kbps.
  • Medium - v.17 which communicates at 14.4 Kbps
  • Slow - v.29 which communicates at 9.6 Kbps
Changing the Fax Speed Adjustment setting to Medium may improve your ability to send a fax over a VoIP network. On most HP fax products the connection speed can be set to a lower speed. Those that do not have a Fax Speed setting generally communicate at medium speed or lower as this was the past standard. Consult your user's manual for information specific to your model. Changing the Fax Speed Adjustment to a lower speed Follow the steps below.
  1. Press Setup .
  2. Select Advanced Fax Setup .
  3. Press OK .
  4. Select Fax Speed .
  5. Press OK .
  6. Select Medium .
  7. Press OK .
  8. Try the fax again. If you continue to have problems faxing, contact your VoIP provider as they may have options to improve the ability to send and receive faxes over VoIP telephone service.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.

CANT SEND FAX THRU VOIP LINE


Make sure baud rate is set to 9600 and error correction mode (ECM) is off. If this does not correct your issue then you may have to contact your provider to adjust your sample rate (packetization). This adjusts the size of the packets and is often a common fix. You may want to run a ping/tracert from command prompt to check for latency and/or packet loss with your ISP. I'm a voip tech and these are the primary fixes for fax issues.
