On the AltiGen IP Phone
The IP phone's System menu includes an item called Auto Discovery. The user can
select YES or NO for this menu item. The factory default is YES.
When you Upgrade Firmware
When you upgrade from firmware that does not support Auto Discovery, Auto
•
Discovery will be disabled by default.
When you upgrade from firmware that does support Auto Discovery, the Auto
•
Discovery setting will carry over.
When the user erases the IP phone configuration by using **2 [enter] in the IP
•
phone menu, Auto Discovery will be enabled by default.
Possible scenarios
During the IP phone's start-up stage, if Enable DHCP is ON and Auto Discovery is
•
set to YES, the IP phone configures its IP address from DHCP, and at the same time,
it gets the MAXCS SERVER address from DHCP option 120. The user is then
prompted to set his extension number and password.
If Enable DHCP is OFF, then the phone's IP address and the MAXCS SERVER
•
address must be set manually.
If Enable DHCP is ON and Auto Discovery is NO, the DHCP option 120 value is
•
not sent to the IP phone. The MAXCS SERVER address must be set manually.
If Enable DHCP is ON and Auto Discovery is YES and DHCP option 120 is set, the
•
IP phone always gets a new IP address, and DHCP option 120 refreshes the value of
MAXCS SERVER, even if MAXCS SERVER already has a value. The screen pauses for
2 seconds while the IP phone gets the MAXCS IP address from DHCP 120.
