One idea would be to cooperate with a rural LEC. For example some of the rural iowa guys make $0.04 cent per minute when people call their phone numbers (cabs billing). You would promote free inbound fax numbers and do a revenue share with the rural lec. You could easily do free inbound fax service for all of your customers because most Rlecs do not agree to bill and keep tarrifs. So... you run your fax service where you get 1 free minute outbound for every 10 inbound faxes. Then your average outbound fax costs would be 1/10th less. So if you did a 60/40 revenue split with the RLEC, you would be able to offer free outbound faxes on a "ratio". The FCC is probably going to close this loop hole in the next 20 years. They have been playing cat and mouse with this for years.
