Answer 1

call collect

Answer 2

If you have a string long enough, I think this can be very cheap, free in fact. :o))

Buy a overseas calling card and pay local line rate for your calls.

Or else get a computer, have one at the other end and make comp to comp calls for free via Skype or Yahoo. You are already on the net anyway, so half the problem solved.

Tap into someone else line and call for free!
