NEC MH150/MH160 Wireless Handset Configuration 3-9
NEC MH150/MH160 Mobile Handset Administration Guide - Revision 2
If OAI is enabled, and an IP address (called the OAI Server IP) is
available to the handset (either via DHCP or Static IP configuration), the
handset will communicate with the OAI Gateway at power-on, and
periodically while it is powered-on. If you don't have a NEC OAI Gateway
installed at your site, you should disable the OAI feature to preserve
network bandwidth and battery life.
Network Config
IP Addresses
There are two modes in which the handset can operate: DHCP-enabled
or Static IP. Select the mode for operation from the IP Address menu:
* Use DHCP Will use Dynamic Host Configuration Protocol to assign an
IP Address each time the handset is turned on. If DHCP is enabled, the
handset also receives all other IP Address configurations from the DHCP
server.
Static IP Allows you to manually set a fixed IP Address. If selected, the
handset will prompt for the IP addresses for each configurable network
component. When entering addresses, enter the digits only, including
leading zeroes. No periods are required.
Regardless of the mode in which the handset is operating, the following
components are required and must be configured as part of the SIP
system:
• Phone IP The IP address of the handset. This is automatically
assigned if DHCP is used. If using Static IP configuration, you must
obtain a unique IP address for each handset from your network
administrator.
• Default Gateway and Subnet Mask Used to identify subnets,
when using a complex network, which includes routers. Both of
these must be configured either with an IP address under Static IP
(not set to 000.000.000.000 or 255.255.255.255) or with DHCP for
the handset to contact any network components on a different
subnet. If configured on the DHCP server, use option 3 for the
