Check RFC messages and open pinholes for call signal addresses in RFQ messages
You can enable call setup between H.323 endpoints when the Gatekeeper is inside the
network. The adaptive security appliance 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 adaptive security appliance 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.
