MWI (Message
Waiting
Indication) Select this to enable Message Waiting Indicator (MWI) function for this SIP
account specified in
Section 10.4 on page 159 . When there is at least one new
voicemail for the SIP account, the voice LED (described in Section 1.2.1 on
page 19 ) turns yellow and the BM2022 sends a beeping tone to the phone
while user picks-up the phone to make calls.
DTMF
DTMF Control how the BM2022 handles the DTMF tone relay to the communication
peer. The DTMF tone is generated by the phone when you push its digit
buttons during a call. One application is to send numbers when trying to do
IVR (Interactive Voice Response) service with server.
You should use the same mode as your VoIP service provider. The choices are:
Out-of-band(RFC 2833) - Follow the RFC 2833 standard and send the
DTMF tones in RTP packets.
In Band - Send the DTMF tones in the voice data stream. This works best
when you are using a codec that does not use compression (like G.711).
Codecs that use compression (like G.729) can distort the tones.
SIP INFO Select this to have the BM2022 send the DTMF tones in SIP messages.

CF Target Select this if you want the BM2022 to forward all incoming calls to the specified
phone number, regardless of other rules in this Call Forward Setting section.
Specify the phone number in the
Unconditional CF Target field.
Note: The Unconditional CF function should be used very carefully, since
enabling this function makes the BM2022 forward all incoming calls to
another phone number, so the user would never know if there are any
incoming calls.

Busy CF Target Select this if you want the BM2022 to forward incoming calls to the specified
phone number if the phone port is busy. Specify the phone number in the
