Permit NAT Applied Unknown Message
|
Specifies how unidentified H.323 messages are handled by the
J-series device. The default is to drop unknown (unsupported) messages.
Permitting unknown messages can compromise security and is not recommended.
However, in a secure test or production environment, this statement
can be useful for resolving interoperability issues with disparate
vendor equipment. By permitting unknown H.323 (unsupported) messages,
you can get your network operational and later analyze your VoIP traffic
to determine why some messages were being dropped.
This statement applies only to received packets identified as
supported VoIP packets. If a packet cannot be identified, it is always
dropped. If a packet is identified as a supported protocol, the message
is forwarded without processing.

Permit Routed Unknown Message
|
Specifies that unknown messages be allowed to pass if the session
is in Route mode. (Sessions in Transparent mode are treated as Route
mode.)
