Best Practice
It is best practice that the below extension numbers marked as reserved are not used. Some of the Reserved extensions are already assigned to backend services. These extension assignments cannot be removed/deleted or reassigned.
Additional information
If you have a site set up with internal dialing codes, and the dialing code is XYZ, extensions such as XYZ555 for example are still reserved. For more information, see Configure Cross-Site Dialing in Admin Console.
