into an external IP address
▪Supports Quality of Service (DiffServ) to prioritize
audio and SIP independently
▪Interworking with SIP telephones, in SD quality or
HD-Voice
▪Secure Streaming Function
▪Sending two streams with identical content
▪A delay between the streams can be configured

The top left corner of the main screen has the
coordinates X=0, Y=0.
▪SCREEN RESOLUTION: Displays the screen
resolution of the monitor the application is
displayed on as it is provided by the operating
system. This may be different from the resolution
defined in the graphic card driver due to the high
DPI scaling feature of the operating system.
