If set to "Yes", FEC will be enabled for audio call. The default setting is
"No".
Configures audio FEC payload type. The valid range is from 96 to 126.
The default value is 121.
Configures audio RED payload type. The valid range is from 96 to 126.
The default value is 124.
Enables the silence suppression/VAD feature. If it is set to "Yes", when
silence is detected, a small quantity of VAD packets (instead of audio
packets) will be sent during the period of no talking. If set to "No", this
feature is disabled. The default setting is "No".
Configures the number of voice frames transmitted per packet. When
configuring this, it should be noted that the "ptime" value for the SDP will
change with different configurations here. This value is related to the codec
used and the actual frames transmitted during the in payload call. For end
users, it is recommended to use the default setting, as incorrect settings
may influence the audio quality. The default setting is 2.
Lists the available and enabled Video codecs for this account. Users can
enable the specific video codecs by moving them to the selected box and
set them with a priority order from top to bottom. This configuration will be
included with the same preference order in the SIP SDP message.
Available video codecs are: H264
When enabled, the video sender will temporarily allocate part of the
bandwidth to one data channel to send FEC data to system, thus to
improve the video quality the receiver gets. Enabling this function will take
up part of bandwidth and reduce call rate. The default setting is "Yes".
Enables/disables RFC5168 mechanism for video calls. RFC5168 allows
SIP party to request the sender to refresh its video frame in H.264, or
refresh the full picture in VP8.The default setting is "Yes".
If set to 0, FEC is not sent by separate port. If set 1, FEC is sent by separate
port. Default setting is 0.
Configures FEC payload type. The range is 96-127. Default setting is 120.
Configures video packetization mode. If set to "Single NAL Unit Mode", the
packetization mode will be negotiated as single NAL unit mode when dial
video calls, if the other party does not support the negotiation, then single
NAL unit mode will be used for video encoding by default. If set to "Non-
Interleaved Mode", the packetization mode will be negotiated as Non-
interleaved mode when dial video calls, If the other party does not support
negotiation, then the Non-interleaved mode will be used for video encoding
by default. The default setting is "Non-Interleaved Mode".
