thepcguru: I agree with you. I use scan to email 99% of the time. But a lot of companies do not have email addresses to send documents. They use online forms, will not give out their personal email addresses, and all the method they allow for sending documents is fax.
I have also encountered now, on 3 occasions, attorneys will not accept scanned documents, even with I already have and use their direct email addresses. I was once told that a fax is a valid binding contact, a scanned document emailed is not. I do not know if that is true, but I was told that.
As far as T.38 faxing is concerned, I use it with 100% success. I do not even have to lower the fax speed or remove the error correction as some sites recommend for VOIP faxing.
The only problem I have ever had was when I setup Phone Power, I tried calling my own number and faxing myself. That did not work, so I asked a friend on Phone Power to fax me. He was unsuccessful as well. The only conclusion I could draw, and this is just a guess, is that a Phone Power to Phone Power call is handled differently and somehow bypasses the T.38.
My friend also tried something different. He took his office phone which is on Verizon, and forwarded that number to my Phone Power phone. Then from his Phone Power number he called the Verizon number which forwarded to my Phone Phone Power number. Using that call forward setup, the fax was successful going Phone Power to Phone Power via a Verizon forwarding number. It seems you have to enter the Phone Power network from the outside in order for T.38 to work.
I never fax anyone who has Phone Power, so it does not really matter to me. When ruthrey99 asked the question, it just brought back some thoughts I had from when I was setting up the Phone Power service.
