Alter trunk directory number

With this command it is possible to change the directory number of a trunk.

If you want to change the number to a new number which is in conflict with the old number, this cannot be done directly. In such cases first change to a random free number and then change to the desired number.

However, references to previous numbers will remain. These references are to be deleted or replaced by the new number. See description of command group 56 listing commands referring to directory numbers.

If no number is indicated, the present directory number is deleted for this trunk line and the extension no longer has a number. The previous number is now vacant, and a call towards this number will receive a vacant tone from the exchange. However, incoming calls on this trunk line will be routed to the trunk’s answering position.
