Wayne, thanks for your opinion, I appreciate.

If I understand correctly, my client would need to buy Castelle's HardWare and install Castelle's software to use it. Then I would have to get information from Castelle documentation on how to automated faxing from within VFP. For me, to do the development and testing, I would have to go to my client business place to work (this is one thing I don't like to do) or buy Castelle for myself.

I understand that Castelle allows them to fax from any workstation without problem, not just the one that is plug to the modem, that would be a small plus. I also see that some peoples recommeded it so it must be a good product.

But, in this case it's a small firm with 5-6 users. Sending about 1000 faxes every second day(or night)to their own customer not the large public. So I'll try the WinFax solution first. Bottom line it look like the least expensive solution even if they have to upgrade a computer for winfax to work.
