Networking Features
The OBi Phone
offers two physical interfaces for networking: Ethernet (described as “WAN” in the configuration) and
WiFi. Both interfaces may be used at the same time, but Ethernet will take precedence in ambiguous cases.
Ethernet Ports
The OBi Phone has a 3-port switch, one of which is connected internally to the phone processor for traffic to and from
the OBi, with the other 2 ports exposed to the outside world via two RJ45 connectors on the back of the devices. The
two exposed ports are labeled SW and PC. The SW port should be connected to the Ethernet switch and the PC port
used to daisy chain a PC or other Ethernet-connected device. While the SW port supports PoE, the PC port does not,
but otherwise the two ports are totally symmetrical.
At present there are no configurable options for either of the external Ethernet Ports.
WAN Interface
The WAN interface on the phone refers to the internal Ethernet switch port that is connected directly to the phone
processor. The following setting groups are available.
VLAN
The OBi Phone supports VLAN tagging in compliance with 802.1p/q. If

is enabled, outbound traffic will be tagged according to the parameters
VLANID
and
VLANPriority
. The phone will ignore inbound traffic that does not belong to the same VLAN.
LLDP
The OBi Phone supports LLDP-MED to automatically discover Network Policy (VLAN and DSCP) settings and perform
other related handshake functions. This feature is enabled using the parameter

IP Address Assignment
The OBi Phone supports 3 methods of acquiring an IP address assigned to its WAN interface. The method to use is
controlled by the parameter

, which can have one of the
following values:
•
DHCP
: Request address assignment from a DHCP server
•

: Request address assignment from a PPPoE server
•
