Responding to an earlier query about toll-free phone service, I use Uni-Tel Communications Group out of Naperville, IL. I made the arrangement years ago through a reseller, and the actual provider has migrated a couple of times, but I have always had good service.
I pay 5.9 cents per minute (billed in tenths of minutes) with no set-up charge and no monthly fee. I get detailed call records every month. I honestly don't know if this offer/price is still available, or if I have been "grandfathered" (in more ways than one - since I have 12 grandchildren). Just FYI, I have the switched toll free number that is the same 7-digits as my area code 918 number. Easier for the grandkids to remember. Uni-Tel is both my long distance and toll-free provider.
