Index
Use this field to assign
line 1
or
line 2
telephone sockets (on
the back of the router) to the information entered in the User
Agent.
DTMF Method
Out-of band Dual Tone Multi-frequency -The Dual Tone
Multi-frequency (DTMF) mode sets how the router will handle
the tones that your telephone makes when you push its buttons.
It is recommended that you use the same mode that your VoIP
service provider uses. Select
RFC 2833
to send the DTMF
tones in RTP packets. Select
Inband
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).
Select
INFO
to transmit DTMF tones out-of-band.
Payload Type
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
.
VAD
Voice Activity Detection (VAD) -detects whether or not speech
is present. This reduces the bandwidth that a call uses by not
transmitting “silent Packets” when you are not speaking.
