DVX IPPBX
If DHCP is selected then the WAN interface will not be configurable as it obtains all its network
parameters from the DHCP server. DHCP should be used cautiously as allIP extensions registerto
the IPPBX system through the WAN interface and as DHCP addresses can change and IP
extensions need to know the address of the IPPBX at all times. It is best practice to configure
WAN address with a Static IP.
PPPoE
DVX IPPBX can be connected to the network via ADSL modem by means of Point-to-Point
Protocol over Ethernet (PPPoE)dial-up. In such a situation, extensions will subscribe to the IPPBX
system through the LAN port, while WAN port can be used for remote extensions.
