must be the same as those on the exchange.
You are not allowed to configure this command on an ISDN interface if there is still a
call on it. This command can take effect only if it is configured when there is no call
on the interface.Alternatively, you can manually disable the interface by executing the
shutdown command, configure the command, and then enable the interface by
executing the
undo shutdown command. The operations, however, will lead to the
disconnection of the call existing on the interface.
