The telco doesn't charge the caller anything. The phone bill charges I was describing are on the 800 number bill sent to the owner of the
800 number, i.e., if you were to call my 800 number from a payphone, I would see the extra 54 cents on my phone bill.On the other hand, if you use the 800 number to access a calling card, the calling card company invariably passes along the payphone surcharge and marks it up somewhat.
There's a pair of line type digits sent along with the ANI. That topic has been discussed in the digest at some length.
The latter, it's to compensate the payphone owner (either COCOT or LEC payphones) who otherwise gets no revenue for the call since separations have gone away and the caller didn't put in any coins.
