Important:
The configuration in MaxAdmin will override the IP phone's local configuration
after the IP phone is registered. If the IP phone's local configuration is
changed while in Basic mode, these changes will be overwritten by MaxAdmin
settings.
Important:
Administrators should perform any updates to the IP phone's firmware after
normal business hours or when the IP phone is not in use. If the IP phone is
in use during an update, not only will the call will be disconnected, but if the
IP phone is powered off by the user during the firmware upgrade, the IP
phone may become unusable.
Configuring Auto-Discovery of Server IP Address
You can configure option 120, in your DHCP server with your MAXCS IP address, so that
the AltiGen IP phone automatically discovers the MAXCS server IP address and only
needs to have the extension and password entered.
Note:
IP phone firmware 2x91 and above is needed for this feature.
In addition to making initial IP phone setup easier, this feature is also helpful when there
is a need to migrate MAXCS to a new IP address. The administrator just needs to update
the new MAXCS IP address in the DHCP server and then reboot all Altigen IP phones.
The phones will automatically pick up the new MAXCS' IP address.
WARNING!
In the event that there are two MAXCS servers in a same network and all
IP phones get their IP address from a single DHCP server, some IP phones
will get the wrong server IP address. You need to disable the auto-
discovery feature for those IP phones that log on to the MAXCS server that
is not configured in the DHCP option 120.
Setting Up DHCP Option 120
Different DHCP servers have different ways to set up options. The following example
uses Microsoft Windows DHCP Server to define option 120. Since option 120 is not
available by default, you must create it.
1. Open the DHCP configuration window.
(Alti-IP 600 and IP 705) When enabled, allows the IP phone to display
workgroup queue status, such as number of queued calls, the current
longest queue time, agent login/logout state by pressing the Down arrow
key.
