SIP IP Phone Models 9143i, 9480i, 9480i CT and 5i Series Phones Release Note 2.3
New Features in Release 2.3
Multiple DHCP Servers
In Release 2.3, the IP Phones can now 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 Option Override 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.
IMPORTANT NOTE
Users currently using multiple DHCP servers on a single network could be affected by this new feature.
