valid range is from 32 - 2048 kbps. 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
Video Bit Rate
not permitted, the video quality will decrease due to packet loss.


Session Level: use AS format in session level

No: 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

H.264 Payload Type
Configures H.264 codec payload type. The default setting is 99. The
valid range is from 96 to 127.
Enable SRTP mode based on your selection from the drop-down
SRTP Mode
menu. The default setting is "Disabled".
Select the Advanced Encryption Standard (AES) key length for SRTP.
It requires to enable the SRTP mode before this setting taking effect.
SRTP Encryption Bit
If select AES 128&256bit, the phone will provide both AES 128 and
256 bit encryption keys length to encrypt the SRTP. If select other
settings, the phone will only provide one of the encryption keys for
SRTP encryption. The default setting is AES 128&256 bit.
