significantly therefore consuming more bandwidth. Lack of bandwidth will
impair the video due to packet loss.
The Default value is 1400, range from 100 to 1400.
It is recommended to use 600~800 if you have an Outbound Proxy or Media
Gateway.
Frame, TMN8 or GOP. The Default setting is Frame.
TMN8 is good for bandwidths larger than 384kbps
Skips bad video frames as they are received
The Default setting is No.
When enabled, all P frames will only have reference to previous I frames.
This method may improve video quality when the network has heavy packet
loss. It will have modest increase in bandwidth usage. The Default setting is
No.
The packetization mode (0 or 1) for the H.264 video packets. The default
setting is 0.
This setting allows the phone to send redundant P-frames of I frames. When
an I frame is delayed or has packet loss, the redundant P-frames will be
used instead. It may make video phone call less prone to errors and thus
make the video stream more robust towards error propagation, but may
increase bandwidth usage. The default setting is set to No.
This parameter specifies whether Adaptive MB Intra Refresh is used or not.
It may protect most important MBs (macro blocks) subjected to packet loss
and to avoid error propagation. The intra-refresh rate is adapted according
to the video packet loss rate. It may increase bandwidth usage. The default
setting is set to No.
Specifies the video packet loss rate for the Adaptive MB Intra Refresh.
Users can choose from: Less than 5%, Less than 10%, Less than 15%,
Less than 20%, Less than 25%. The default setting is set to Less than 10%.
Using these settings, users can configure ring or tone frequencies based on
parameters from the local telecom provider. By default, they are set to the
North American standard.
