Kevin, I've written an App the uses Symantec Winfax V10 to control the sending of all faxes within my company. Using the SDK object, I've written an app that can send faxes, perform retries, inform the user via email when the fax has been sent/failed etc. We send about 1000 faxes per day, all for the cost of £80 for Winfax, and some elbow grease within VFP.

Let me know if you want examples/any other help.

Regards
