To set conference parameters, do the following:
Step 1
Select

Conference
, and then set the parameters listed in Table 6-2.
Table 6-2 Conference parameters
Parameter Description
Audio protocol This specifies the audio protocol used by the terminal to encode and
decode the audio.
Video protocol This specifies the video protocol used by the terminal to encode and
decode the video. In a non-multi-stream conference, the video
protocol is the video protocol used by the local terminal.
Video resolution You can select a proper format based on the video protocol that is
already set.
When the video protocol is set to
auto
, the video format can be
Sharp
or
Smooth
.
When Sharp is selected, the system prioritizes the frame rate. When
Smooth is selected, the system prioritizes the video resolution.
Video frame rate This specifies the video frame rate, that is, the frequency at which
the imaging device produces unique frames. The higher the frame
rate, the smoother and clearer the video. It is recommended that you
select Auto .
Enable H.239 After this check box is selected, presentations can be shared during
point-to-point calls.
Dynamic bandwidth If this function is enabled, when the ratio of the packet loss caused
by insufficient bandwidth in the network increases, the terminal
decreases the conference bandwidth automatically until the packet
loss does not occur constantly in the network or the conference
bandwidth is decreased to 64 kbit/s. Using the policy of dynamically
adjusting the bandwidth, the terminal can stabilize the bandwidth
within one minute after packet loss occurs in the network.

When the network condition is good, select Disable .

When the network condition is poor, select Enable .
Conference line
type
This specifies the type of the line used during a multipoint
conference.
If
Auto is selected and the terminal is registered with a GK, an IP
line is preferentially used for the multipoint conference.
Conference
bandwidth
The default value is Normal .
When the terminal accesses network using an IP line, set the
conference bandwidth to Limited to enhance the quality of the
video conference.
Select conference
control operation
This specifies the conference control options to be displayed on the
Conference Control
screen.
Step 2 Save the settings.
