Figure 3: Enable DHCP VLAN

After user enables this feature, the phone will disable LLDP VLAN setting and try to read VLAN setting from
DHCP to override manual setting. Firstly, the phone will send discover package and receive offer package
for option 132 (VLAN ID) and option 133 (VLAN priority) via DHCP server.
Figure 4: DHCP Option 132 & 133
If one of Option 132 or Option 133 is not empty, the phone will read values in these two options. However,
if Option 132 and Option 133 are both empty, the phone will retrieve the value of Option 43 for VLAN ID
and priority. If VLAN ID and priority are both valid, VLAN setting will take effect after phone rebooting; if one
of the value is invalid, DHCP VLAN setting won't override manual setting.

Ability to Configure Record Button

This option can be found under web UIAccountCall Settings, it allows users to configure the DTMF
that will be sent once record button is pressed during the call.
