When true / 1 the FXO port will use a shorter off-hook calibration delay. This is sometimes necessary in order to properly decode Type-II Caller ID information which is sent shortly after an FXO port goes off hook. Defaults to 0 unless opermode is "JAPAN" then it will default to 1. This functionality was ported from the wctdm.c driver. DAHDI-854.
