Enter a name to easily identify the codec profile You can select the codec
profile in the SIP Peers section.
This list includes all available codecs. If you want to use a certain codec,
select it and click Use Codec. The codec will be moved to the Selected
Codecs list. The G.729 codec can only be used after you have purchased
and activated a license. See License Activation for more information.
By default, the G.711 A-law and G.711 µ-law codecs are selected. If you
want to delete a certain codec, select it and click Remove Codec. The
codecs are used according to their position in the list, with the first codec
being the first to be used. To change the order, use the Up and
Down buttons.
Interval between RTP packets in an RTP stream. Also known as
packetization time or RTP frame size.
Voice
activity
detection:
If you activate voice activity detection, silence during a conversation is
detected, and the data rate is reduced.
Comfort
Noise
Generation:
If you enable this parameter, packets with low artificial background noise
are sent to fill periods where no data packets are received from the SIP
peer. This helps prevent the other party from thinking the transmission
has been lost (because of the silence) and hanging up prematurely.
Note: Support for this feature depends on the type of Diva Media Board
present in the system. If the hardware does not support this feature, the
setting is ignored.
Support
comfort
noise
payload:
If you enable this parameter and VAD is configured for the codec used for
the call, periods of silence will be replaced by sending a special "comfort
noise" signal to the SIP peer. This allows a supporting SIP device to
generate appropriate artificial background noise in order to remove the
impression of the call being interrupted.
If the SIP peer does not support this type of event, this setting has no
effect.
Enable this parameter if you want to use the noise suppressor
functionality.
If you enable this parameter, the audio echo canceller is active for calls to
or from the PSTN.
This option enables DTMF and fax tones to be sent and received as RTP
events instead of audio signals.
G.726, iLBC, RT Audio, and DTMF have a dynamic RTP payload. If you
enable this option, Diva SIPcontrol sets the values automatically. If the
endpoint cannot handle the automatically set value, enter it manually
under Manual payload type value.
