no it's not a ACD or hunting group.
The problem is that the costumer has remove the extension with EMG, but something had gone wrong, because the can't make a new extension with the same number.
I had then tryed to make a new extension with winfiol,
but it replyes with EXTENSION ALREADY ASSIGNED. i have then tried to make EXDDP and KSDDP, then it tells me that the extension doesn't exist.
