Chapter 10 The VoIP Account Screens Table 73 Feature (continued) LABEL MWI (Message Waiting Indication) DTMF DTMF DESCRIPTION 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. 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. Call Forward Setting Unconditional CF, Unconditional CF Target Select this if you want the WiMAX Device 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. Busy CF, Busy CF Target No Answer CF, No Answer CF Target, No Answer CF Waiting Time Call Waiting Setting Call Waiting Call Waiting Reject Time Note: The Unconditional CF function should be used very carefully, since 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. Select this if you want the WiMAX Device to forward incoming calls to the specified phone number if the phone port is busy. Specify the phone number in the Busy CF Target field. If you have call waiting, the incoming call is forwarded to the specified phone number if you reject or ignore the second incoming call. Select this if you want the WiMAX Device to forward incoming calls to the specified phone number if the call is unanswered. Specify the phone number in the No Answer CF Target field on the right. Specify the time to wait before forwarding incoming calls in the No Answer CF Waiting Time field. Select this to enable call waiting for this SIP account on the WiMAX Device. Enter time to wait before rejecting a call when call waiting is enabled. 10.6 Dialing Click VoIP > Account 1 (or Account 2) > Dialing to configure dialing timeout values.
