# Some providers charge 1p per minute, but make a connection charge
# as soon a call is established, usually about 3-5p.

# All charges quoted in UK pence/minute # (inc. VAT)

# Our strategy here is to keep up the line initially for at least 4p/2
# worth of seconds, so that the connection charge is not more than the
# 2/3 of the cost of a connection. In other words the minimum call cost
# here is 4p*3/2, or 6p, that is just about the same as BT, except that
# the minimum cost buys less time. However the cost of subsequent seconds is
# smaller, unless one takes into account F&F and PL discounts, then it is
# roughly the same.

# Given that reconnecting cost of 4p we also don't want to hang up
# as soon as the line becomes unused; we wait another 4p/2 worth of
# seconds.
