It uses timeouts just like calling from home.  To call number 234-5678
in Athens, Greece using a calling card you would enter:

01-30-1-234-5678-[Timeout or #]
                               {bong AT&T or whatever}
                                [Calling card number]
                               {Thanks for using AT&T or whatever}

On a related question, although I have been successful doing the
above in the past, I recently tried it from a Boston payphone.  To my
surpise after the thanks for using AT&T recording, an AT&T operator
answered the phone.  She said that I could not use my calling card to
dial that country from that payphone.  So I moved to another one,
tried again, same thing.  This time the operator said that the country
I am calling has disabled calling card calls.  This does sound right
to me.  Trying the same thing from a hotel room was successful.  Can
anyone explain the above?
