The Add/Edit H.323 Policy Map pane lets you configure the security level and additional settings for
H.323 application inspection maps.
Fields
• Name—When adding an H.323 map, enter the name of the H.323 map. When editing an H.323 map,
the name of the previously configured H.323 map is shown.
• Description—Enter the description of the H.323 map, up to 200 characters in length.
• Security Level—Shows the security level and phone number filtering settings to configure.
• State Checking—Tab that lets you configure state checking parameters for the H.323 inspect map.

Check RFC messages and open pinholes for call signal addresses in RFQ messages
Note You can enable call setup between H.323 endpoints when the Gatekeeper is inside the
network. The ASA includes options to open pinholes for calls based on the
RegistrationRequest/RegistrationConfirm (RRQ/RCF) messages. Because these RRQ/RCF
messages are sent to and from the Gatekeeper, the calling endpoint's IP address is unknown
and the ASA opens a pinhole through source IP address/port 0/0. By default, this option is
disabled. You can enable this option by setting the option in the H.323 Inspect Map.
