TELEPHONY SETUP

To access the TELEPHONY SETUP setting window, click on the TELEPHONY SETUP button under the VOICE tab.
The TELEPHONY SETUP page contains
TELEPHONY CONFIGURATION,
CODEC PRIORITY & PACKET INTERVAL, and
LOCALE SELECTION to be specified by your ISP.
Index allows you to select the current port you want to configure. This
directly relates to the FXS1 or FXS2 ports on the back of the unit.
Echo Cancellation (EC) - G.168 is an ITU standard for eliminating echo.
Select Enabled to cancel the echo caused by the sound of your voice
reverberating in the telephone receiver when you speak.
Voice Activity Detection (VAD) - detects whether or not speech is
present. This lets the router reduce the bandwidth that a call uses by not
transmitting "silent Packets" when you are not speaking.
Out-of band Dual Tone Multi-frequency (OOB DTMF) - Select Enabled
(RFC 2833) to send the DTMF tones in RTP packets. Select Disabled
(G.711) to include the DTMF tones in the voice data stream. This
method works best when you are using a codec that does not use
compression (like G.711).
A Payload Type is a number from 96 through 127 that identifies the
type of payload carried in the packet. For example, a payload type of
122 denotes a fax payload. This field is only active when the DTMF
method is set to RFC 2833.
Inter-Digit Timer determines the amount of time that will elapse
between sending dialed digits when making a VoIP telephone call.
