callprogress and/or busydetect are known to have issues, especially outside 
the US....that said there's hangup detection as well I think that's 
problematic sometimes (Japan seems to trigger this problem pretty 
reliably).  This all relates to the FXO (the red ones on a Digium TDM400P 
board) modules, so maybe try turning it off.
