asterisk users - Jul 2004 - will digium hardware and asterisk function in asia (korea)?

I am looking at asterisk as a PBX for our import/export business which
currently has offices in the US and Korea.  Asterisk seems great for our
purposes, but I'm somewhat of a telcom newbie and have some questions.
Does anybody know anything about the phone system in Korea with respect
to whether or not digium hardware and * will function the same as they
would in the states?  

I understand that the voip part is probably location-agnostic, but what
about the POTS?
