s = Start. Used primarily for dialplans that enter a context with no
other extension information. Think of a non DID phone line, call comes
in, and we may only know that the line is ringing and nothing else. Even
if you knew callerid, you have to still have a place to start. You can
also think about s as a place to place part of the dialplan that you
don't want callers to get back to unless they have passed through other
functions.

t = Timeout. Used for when calls have been inactive after a prompt was
played. Also used to hang up a line that has been idle.

h = Hangup. Used to clean up a call. Could be used to play a goodbye
message before hanging up. Also seemingly used by the calling card
people to record end of call for billing purposes.
