Call Park and Pickup Call park and pickup lets you put a call on hold (park) and then continue the
call (pickup). The caller must still pay while the call is parked.
When you park the call, you enter a number of your choice (up to eight digits),
which you must enter again when you pick up the call. If you do not enter the
correct number, you cannot pickup the call. This means that only someone
who knows the number you have chosen can pick up the call.
You can have more than one call on hold at the same time, but you must give
each call a different number.
Call Return With call return, you can place a call to the last number that called you (either
answered or missed). The last incoming call can be through either SIP or
PSTN.
Country Code Phone standards and settings differ from one country to another, so the
settings on your BM2022 must be configured to match those of the country
you are in. The country code feature allows you to do this by selecting the
country from a list rather than changing each setting manually. Configure the
country code feature when you move the BM2022 from one country to
another.
Do not Disturb
(DnD) This feature allows you to set your phone not to ring when someone calls you.
You can set each phone independently using its keypad, or configure global
settings for all phones using the command line interpreter.
Auto Dial You can set the BM2022 to automatically dial a specified number immediately
whenever you lift a phone off the hook. Use the Web Configurator to set the
specified number. Use the command line interpreter to have the BM2022 wait
a specified length of time before dialing the number.
Phone config The phone configuration table allows you to customize the phone keypad
combinations you use to access certain features on the BM2022, 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 BM2022. Enter
*99# in your phones keypad to have the BM2022 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 BM2022 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 BM2022 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.
