FYI 60/1 measn first 60 seoncd billed then each 1 /60th of a minute<br>
<br>
so 1minute 25 second call is billed as 1 minute 25<br>
45 second as one minute<br>
wher the first number is minimum seconds<br>
<br>
so 6/6 is first 6 seconds no matter what then every block of 6 seconds..<br>
<br>
6/1 well you get the point..<br>
<br>
its like cell carriers..<br>
<br>
where some bill per minute others like canada fido per second..<br>
<br>

<br>not been a single case that was prosecuted, and for the payphone<br>operator (providing they meet the compensation requirements of the FCC<br>rules - 13.65 comes to mind but I havent owned a payphone business since<br>
1998 so I may not remember correctly) to make up some wild story about<br>how it was a kid or something (which doesnt negate the payphone<br>operators claim to compensation). An elligible payphone must be<br>available for the general public to get access to it.
<br><br>All payments are typically made through clearinghouses as opposed to<br>inidvidual carriers processing the billing. This makes fraud tracking<br>slightly easier since all the calls are there. They have kept averages
<br>of total calls by a payphone to compensatable numbers, carrier averages<br>(ie mci, sprint, at&t, etc) and stuff that way.<br><br>If someone were to use an auto dialer to call a tollfree they violate at<br>least 47 CFR
64.1200 and I think a criminal statute too (I dont remember<br>where in the USC it is anymore, but there is one for that).<br><br>According to the FCC rules back in 1997-98 on this matter even if fraud<br>is suspected you must pay the payphone operator. They also talk about
<br>civil damages being sought, but that doesnt preclude criminal charges,<br>only gives you easy rights to sue, which of course costs money and the<br>burden of proof is then upon you.<br><br><br>> I understand that within the PSTN there is a 2-bit value associated
<br>> with the class of phone that the call is placed from (normal,<br>> payphone, prison-phone). If voip/pstn gateways started passing this<br>> on it might make it easier for folks to guard against payphone scams
<br>> by configuring their asterisk to only answer the 800 calls made from<br>> normal residential phones.<br><br>Any reasonable provider should be able to block those calls, however in<br>a blocking situation its all or nothing. If you have ani you can look
<br>for the same number calling over and over and reject it that way. You<br>should have ani with a tollfree.<br><br>The additional info is commonly not sent and afaik there is no<br>'standard' way to send that. SIP IM might work (that is how verisign
