Parameter Description
Video Clarity
This option is enabled by default. It is used to improve the
clarity of video received from an endpoint which has low
bandwidth and/or low resolution.
Lost Packet
Recovery
Lost Packet Recovery (LPR) is an algorithm designed to
protect IP video calls against the impact of network packet
loss. This option is enabled by default. In case of packet loss
during network transmission, the packet recovery mechanism
will be automatically activated if the endpoint experiencing
packet loss also supports the LPR protocol. This function can
effectively improve the decreased video quality caused by
packet loss.
Echo Suppression
This option is enabled by default. It is used to prevent the
sound of near site echoing being played to the far site(s).
