Enter H.265 codec payload type. The valid range is from 96 to 127. The default value
is 114.
If set to "Yes", the device will disable presentation and will not receive presentation
during video call. The default setting is "No".
If it is enabled, the initial INVITE packet sent from GVC to server will carry BFCP
media information. If not, the related media info will be included in re-INVITE packet
and the BFCP negotiation with some specific servers might be failed.
It is used to select the H.264 image size from "720P" or "1080P". The default setting
is "1080P".
Select the H.264 profile type from "Baseline Profile", "Main Profile", "High Profile" or
"BP&MP&HP". The default setting is "BP&MP&HP". Lower profile type is easier to
decode, while higher level has higher compression ratio. For device with low CPU,
select "Baseline Profile". Also, "Baseline Profile" is likely to be used in a video
conference that has high demand for the video quality.
It is used to configure the bit rate of the video. The video bit rate can be adjusted
based on the network environment. Increasing the video bit rate may improve video
quality if the bandwidth is permitted. If the bandwidth is not permitted, the video quality
will decrease due to packet loss. The default setting depends on presentation H.264
image size.

Presentation H.264 Image Size = 1080p, Video Bit Rate can be set to a value
from 1024kbps to 4096kbps

Presentation H.264 Image Size = 720p, Video Bit Rate can be set to a value from
512kbps to 2048kbps
It is used to configure the video frame rate for presentation. The options are 5fps,
10fps and 15fps. The default setting is 15fps.
It is used to select the transport protocol used for BFCP. Users can choose from
Auto/UDP/TCP. The default setting is "UDP". If "Auto" is configured, the device will
automatically switch between "UDP" and "TCP".
It is used to set if the device will enable the SRTP (Secured RTP) mode. It can be
selected from dropdown list:
 Disable
 Enabled but not forced
 Enabled and forced
SRTP uses encryption and authentication to minimize the risk of denial of service.
(DoS). If the server allows to use both RTP and SRTP, it should be configured as
"Enabled but not forced". The default setting is "Enabled But Not Force".
