Seems like it's always been sorta like that for us, we'll go for months and all the sudden we get an extra thousand or two bucks in a check...

I think the deal is the 900 provider bills the customer on their phone bill, they have to wait for the customer to pay the local telco, the telco to pay them, and them to pay ccbill... it was a similar deal years ago when I worked with a tech support line that used 900 number billling.
