Table 108 Voice Features
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 BM2022w 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 BM2022w 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 BM2022w 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 BM2022w wait a specified length
of time before dialing the number.
