Issue 11.0
The ML440 has two sets of keys:
Three soft keys that are dedicated depending on the state of the call and four programmable keys.

The three dedicated soft keys are predefined depending on the state of the call. For example once
a person is in conversation, these three keys are Hold / Conf./ Transfer. This makes it easy for end
users to receive and move calls around.
Four programmable keys on the base on the handset. The keys can be programmed for many of

the same features that are supported on the DT7XXX desk sets.
Line key programming is flexible. The following is an example for the first three programmable keys:
Line Keys 1 and 2 = CAP Keys

Line Key 3 = Intercom Key

Powering the AP20
The AP20 can only be powered using Power over Ethernet (PoE) 802.3af.
A PoE switch is a switched hub that also provides power over the spare pairs. The switch can be used
with other devices than the IP telephones and detects whether or not power is needed. Using a PoE
switch makes it easier to protect the IP telephones from loss of power (connection of the PoE switch to
an UPS).
Updating the AP20 and ML440 System Firmware
The firmware on base stations and handsets is updated remotely using the HTTP configuration interface
to download firmware files from a TFTP server. Updating base station firmware involves an automatic
reboot of the base station at the end of the firmware download. This will drop any active calls and in
addition updating the handset firmware can take several hours. It is recommended updates are
performed after normal business hours. Refer to the ML440 and AP20 System Installation Guide for
detailed information.
