802.1x Mode
This option allows the user to enable/disable 802.1x mode on the phone. The default
value is disabled. To enable 802.1x mode, this field should be set to EAP-MD5. Once
enabled, the user would be required to enter the following information below to be
authenticated on the network:
• Identity
• MD5 Password
Line Keys x
This allows the user to configure the account mapped to each line key, as well as
enabling Shared Call Appearance for the line. Options available for Key Mode are :
1. Line
2. Shared Line
Multi Purpose Keys
These options are used to assign a function to the corresponding Multi Purpose Key.
Options available are:
1. Speed Dial
2. BLF (Busy Lamp Field)
This option has to be supported on the PBX and it indicates the status of the
extension. The three possible states are idle (green), busy (red), ringing
(blinking red).
3. Presence Watcher
This option has to be supported by a presence server and it is tied to the “Do
not disturb” status of the phone.
4. Eventlist BLF
This option is similar to the BLF option but in this case the PBX collects the
information from the phones and sends it out in one single notify message.
PBX has to support this feature.
5. Speed Dial Via Active Account
This option will act just like speed dial, but based on the current active
account. For instance, if the phone is offhook and account 4 is active, it will
call the configured speed dial number using account 4.
6. Dial DTMF
This option will allow users to enter a series of DTMF digits as configured in
the UserID field for the MPK during the call. When using Dial DTMF, “Enable
MPK Sending DTMF” (under Advanced Setting) has to be set to “Yes”. This
option is not binding to the account.
7. Call Return.
The last answered calls will be dialed out. The username and UserID should
be blank when using Call Return. This option is not binding to the account.
Note:
The functions from 1 to 5 are connected to one of the accounts and have target
username and UserID.
Time Zone
This parameter controls the date/time display according to the specified time zone.
If “Allow DHCP Option 2 to override Time Zone setting” is checked, the time zone will
be overridden by the DHCP server.
