Phone config The phone configuration table allows you to customize the phone keypad combinations
you use to access certain features on the BM2022w, 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 BM2022w. Enter *99# in your
phone’s keypad to have the BM2022w 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 BM2022w 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 BM2022w 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).
