H.323 Inspect Map
The H.323 pane lets you view previously configured H.323 application inspection maps. An H.323 map
lets you change the default configuration values used for H.323 application inspection.
H.323 inspection supports RAS, H.225, and H.245, and its functionality translates all embedded IP
addresses and ports. It performs state tracking and filtering and can do a cascade of inspect function
activation. H.323 inspection supports phone number filtering, dynamic T.120 control, H.245 tunneling
control, HSI groups, protocol state tracking, H.323 call duration enforcement, and audio/video control.
