Obtain OM IP Address
OM10 and OM20 start DHCP service by default, and automatically obtain an IP address on the LAN;
users can use the factory default IP address if it is unable to be obtained (e.g. when connected directly
with a computer).
OM100 and OM200 use a static IP address by default.

DHCP Used in Network
Users can dial "# #”to obtain the current IP address of the device and version information of
firmware using the telephone connected to a FXS port after the equipment is powered on.
If the OM is only configured with FXO ports for analog trunks without FXS ports (e.g.
OM10-4FXO or OM20-24FXO), users can dial into the OM by connecting a PBX extension line
or CO line to a FXO port, and press "# #" to obtaining the current IP address of the device and
version information of firmware.

Fixed IP Address Used
¾
If the DHCP service on the network is not available or the OM is directly connected with a
computer, the OM will use the factory default IP address.
¾
A user could fail to log in with the default IP address if the IP address of user’s computer
and the default OM IP address are not at the same network segment. It is recommended that
the IP address of user's computer is changed to be identical with the same network segment.
For example, if the OM IP address is 192.168.2.240, it is recommended to set the
computer’s IP address to any address at the network segment of 192.168.2.XXX.
z
PPPoE Used
In “Basic Configuration> Network Configuration”, the OM will automatically obtain the WAN
address returned by access network after PPPoE service is started and user name and password
are set. Users can dial
“
# #
”
on the OM to receive the IP address and version information of
firmware.

IP Address Port Configuration of Equipment
It is typically required to fill in the port when using DDNS since the router possibly maps to a
different port in port mapping.
Normally, it is unnecessary to fill in the port value.
