H.323 vul can affect network core components

[REN-ISAC <dodpears () INDIANA EDU>]

A H.323 protocol-level vulnerability can be exploited to produce a denial of service attack. The vulnerable devices 
include network core components such as firewalls, routers, and proxies that are configured for VoIP and 
videoconferencing support - e.g. a firewall that is configured to dynamically open ports for H.323 or a router that 
provides H.323 gatekeeper.
