MWI (Message
Waiting
Indication)
Select this to enable Message Waiting Indicator (MWI) function for this SIP
account specified in Section 10.4 on page 163. When there is at least one new
voice mail for the SIP account, the voice LED turns yellow and the WiMAX
Device sends a beeping tone to the phone while user picks-up the phone to
make calls.
DTMF
DTMF Control how the WiMAX Device 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 WiMAX Device send the DTMF tones in SIP messages.

enabling this function makes the WiMAX Device forward all incoming
calls to another phone number, so the user would never know if there are
any incoming calls.
