Number ranges

We use special telephone number ranges at the events.

Range Use / Reserved for
1000 - 1999 Orga / Event / Venue
2000 - 2099 Eventphone / PoC
2100 - 9899 public range
9900 - 9999 Internal, special services, services that offer added value for several users.

Just because a number is not listed in the phone book does not mean that it is not used.

If, during the creation of a number in GURU, a message appears telling you that the extension is already in use, then this is correct. There is no reason to open a support ticket.
