Command History
Usage Guidelines The max-dn command limits the number of extensions (ephone-dns) available. The maximum number

number of extensions you can set using this command, as shown in this example:
Router(config-telephony-service)# max-dn ?

Note You can increase the directory numbers; but after the maximum allowable number is configured, you
cannot reduce the limit of the directory numbers without rebooting the router.
