Faxing with Vonage and HP OfficeJet 6310

I've read many complaints/challenges with faxing and vonage. I tried both setting the fax to 9600bps (slowest it will go) and dialing the *99 before the number. Neither of which worked for outbound faxing. Please help, this may force me to rip out vonage...

Did you disable ECM?

See http://www.voipmechanic.com/faxsettings.htm

Disabling ECM or error correction mode is a good start. You may need to call vonage tech support and have them change your packet size to 10ms, and to make sure your buffer is turned up all the way. If it still isn't working then your internet connection may not be strong enough to fax over VOIP. sorry dude

I surely have enough bandwidth for a fax, 25MB down and 8MB up, I have a crazy fast comcast connection

I turned off ECM and still no luck, I cannot even get the two fax machines to "connect" I never hear them try and negotiate.

Well if you tried all of that and you are still having problems, maybe its not Vonage that is the problem.

You mentioned not hearing the the faxes try and negotiate. I imagine you are used to hearing this and havent shut that sound off.

Try taking a normal phone, or even your regular Vonage line and call the phone number you are trying to fax to. Make sure you hear the other fax machine sending tones back. If you dont, then stressing out over bandwidth and hardware configs wont help you at all.

Good luck

Yep, calling fax with phone works fine, fax machine worked before vonage. Only thing that's changed in Vonage..! Evil or Very Mad

post your ping stats.

Click on start button go run. In the box type cmd. Click ok. In the black screen that comes up type:

ping google.com -n 50

post packets lost and % and approximate round trip times.

I am curious as to why you think disabling ECM is good start. I also see some posts where the advise is to also reduce speed.

Seems like VoIP is turning the clock back on FAX. No ECM/ slow-sppeds was what all fax machines did 10-15 years ago. I was looking forward to color faxing Rolling Eyes
