WiMAX Device Configuration User’s Guide

Phone config The phone configuration table allows you to customize the phone keypad
combinations you use to access certain features on the WiMAX Device, such
as call waiting, call return, call forward, etc. The phone configuration table is
configurable in command interpreter mode.
Firmware update
enable / disable
If your service provider uses this feature, you hear a recorded message
when you pick up the phone when new firmware is available for your WiMAX
Device. Enter *99# in your phone’s keypad to have the WiMAX Device
upgrade the firmware, or enter #99# to not upgrade. If your service
provider gave you different numbers to use, enter them instead. If you enter
the code to not upgrade, you can make a call as normal. You will hear the
recording again each time you pick up the phone, until you upgrade.
Call waiting This feature allows you to hear an alert when you are already using the
phone and another person calls you. You can then either reject the new
incoming call, put your current call on hold and receive the new incoming
call, or end the current call and receive the new incoming call.
Call forwarding With this feature, you can set the WiMAX Device to forward calls to a
specified number, either unconditionally (always), when your number is
busy, or when you do not answer. You can also forward incoming calls from
one specified number to another.
Caller ID The WiMAX Device supports caller ID, which allows you to see the originating
number of an incoming call (on a phone with a suitable display).
REN A Ringer Equivalence Number (REN) is used to determine the number of
devices (like telephones or fax machines) that may be connected to the
telephone line. Your device has a REN of three, so it can support three
devices per telephone port.
QoS (Quality of
Service)
Quality of Service (QoS) mechanisms help to provide better service on a
per-flow basis. Your device supports Type of Service (ToS) tagging and
Differentiated Services (DiffServ) tagging. This allows the device to tag voice
frames so they can be prioritized over the network.
SIP ALG Your device is a SIP Application Layer Gateway (ALG). It allows VoIP calls to
pass through NAT for devices behind it (such as a SIP-based VoIP software
application on a computer).
