None: no modifications in the session format.
Note: Please do not modify this setting without knowing the session format
supported by the server. Otherwise, it might cause video decoding failure.
Specifies the H.264 codec message payload type format. The default
setting is 99. The valid range is from 96 to 127.
If set to "No", the device will be unable to receive the presentation stream
in video calls and video meetings. Default is "Yes".
Initial INVITE SDP contains presentation media.
Selects the H.264 image size. Users can select 1080P or 720P.
Select the Presentation H.264 Profile Type from "Baseline Profile", "Main
Profile", "High Profile" and "BP&MP&HP". The default setting is
"BP&MP&HP".
The lower the profile type is, the easier the packet can be decoded.
However, higher level has high compression ratio. For device with low
CPU, select "Baseline Profile" to play record; "Baseline Profile" is more
likely to be used in a video conference that has high demanding for the
video quality. Select among the three types to achieve best video effect.
Configures 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. Video Bit Rate
can be set to integer value from 512kbps to 2048kbps.
Configure the video frame rate for presentation.
Defines transport protocol used for BFCP. Users can choose from
Auto/UDP/TCP. The default setting is "UDP" first, if not supported, then
choose "TCP". If choose "Auto", automatically switches between "UDP"
and "TCP".
Sets if the phone system 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 "Disable".
