## 5601
Extension directory number

Using this command it is possible to alloc the required number to an extension’s line position (ppiii).

If this line position already has a directory number it will be overwritten. Command 5902 Line position-directory number will read the directory number of a certain line position. However, references to previous numbers will remain. The references are to be deleted or replaced by the new number.

See the description of command group 56, where the commands that refer to directory numbers are listed.

If no number is indicated, any previous directory number for this line position is deleted and the line position no longer has a number. The previous number is now vacant, and a call towards this number encounters a vacant tone from the exchange. However, the telephone on this line position may still be used for outgoing calls.
