MITEL WEB UI

Note: In the Mitel Web UI, the "Disabled" download option performs the same
function as the "-1" in the configuration files (ignores DHCP options).

MULTIPLE DHCP SERVERS

The IP Phones can receive messages from multiple DHCP servers.
After the phone receives its first DHCP message, it listens for a specific time period, for more
DHCP messages. If the first DHCP offer contains configuration server information (Options 43,
66, 159 or 160), then the phone times out and continues using the first DHCP offer, without
listening for more DHCP offers. If the first DHCP message contains no configuration server
information, the phone continues to listen for other DHCP messages. If the second DHCP
message contains configuration server information and other conditions, the phone chooses
the second DHCP message over the initial DHCP message.
Note: If the DHCP Download Options parameter is enabled with a value (Option 43,
Option 66, Option 159, or Option 160), the phone checks the override option setting
before timing out
WARNING: USERS CURRENTLY USING MULTIPLE DHCP SERVERS ON A
SINGLE NETWORK COULD BE AFFECTED BY THIS FEATURE.
