Cisco IP Phones that can be supported by the
Catalyst 4224.
You cannot reduce the allowable
Note
number of Cisco IP Phones once the
maximum allowable number is
configured, without rebooting the
Catalyst 4224.
Step 4
Set the allowable number of directory numbers
that can be supported by the Catalyst 4224.
You cannot reduce the allowable
Note
number of the directory numbers
once the maximum allowable
number is configured, without
rebooting the Catalyst 4224.
Step 5 (Optional) Configure the time interval between
keepalive messages sent by Cisco IP Phones to
the Catalyst 4224. E This setting is effective

back to an extension number for the purposes of
caller ID display, received, and missed-call lists.

Cisco IP Phones to other phone numbers (IP and
non-IP phone numbers).
