I believe the usual term is a "phone bill".
If you're refering to a line called something like:
FCC MANDATED ACCESS CHARGE
which is probably $6.50, its correct label should be:
EXTRA MONEY THE FCC LETS US COLLECT
since it is simply part of your monthly phone rate.
Back at the time of the Bell breakup, the access charge was a temporary band-aid the FCC added to make up for part of the previous subsidy from deliberately overpriced interstate long distance rates. It should have gone away in a few years once the telcos went to the states to adjust their rates to include it, but that never happened.
Some people think that they shouldn't have to pay it if they never make toll calls but they are wrong. The niggly reason is that even if you never call anyone long distance, other people can call you so your phone is still connected to the long distance network. The real reason is the one above, it's just part of your phone rate.
