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

section. Specify the phone number in the Unconditional CF Target field.

CF Target

 

 

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.

 

 

Busy CF,

Select this if you want the WiMAX Device to forward incoming calls to the

Busy CF Target

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.

 

 

No Answer CF,

Select this if you want the WiMAX Device to forward incoming calls to the

No Answer CF

specified phone number if the call is unanswered. Specify the phone number in

Target, No

the No Answer CF Target field on the right. Specify the time to wait before
