I am using fax machine pretty well. I am thinking to use the fax modem by utillizing the fax function in Window XP. As you know, Window XP has fax function inside. Does anybody have any experience in this?

I guess nobody has any experience on this topic. I tried bymyself and found that the Fax Program in WIN XP did not answer the the call and I could not receive the fax to computer. I travel a lot and I want to read the fax from any place through internet.

I've never tried this but I can offer some pointers.

If you tried this using regular landline or other VoIP services and it worked, then it should work similarly with Ooma.

If you have a Telo, you need to go into and turn on fax mode in order to receive a fax with max success rate. Not sure why the modem is not picking up.

When you send, you need to use dialing prefix *99 for max success rate.

Check this out:

FYI, I use for free incoming faxes to my email inbox. Drawbacks: need to keep number active at least every 30 days; I call myself, leave a msg every month. Only 206 area code numbers available.

I set up with dedicated fax line with fax mode turned on. It seems that the computer does not pick up the signal from OOMA line.

You have ooma's phone port connected to the modem line in and your phone connected to the modem line out?

I did not connect any phone with the fax. It is dedicated to fax only.

I tried to send the fax out with modem omly and failed. The other party got the signal but their fax did not recognize my signal and did not pick up the signal.

Following is a site that may help with VoIP faxing. It contains general instructions for fax setup, and setup instructions for various brand name fax machines. ... evices.htm

One suggestion that sounds promising is as follows:

Try placing a DSL filter in "reverse position" between the ATA (Ooma Device) and the fax machine (to cut down on "noise").

Faxing using Ooma phone service is just hit and miss until Ooma impliments faxing modes, "Store and Forward FoIP (T.37) fax standard", or "Real Time FoIP (T.38) fax standard".
