Abstract
A system and method for providing multimedia communication between a firewall protected, LAN based endpoint and an endpoint that is external to the LAN. A logical port of a multimedia communications control unit is attached to the LAN behind the firewall. Another logical port of the multimedia communications control unit is attached to the external endpoint. Multimedia communication data, consisting of call management data and media data, can be exchanged between the endpoints via the multimedia communications control unit. The multimedia communications control unit allows only multimedia communication data that strictly adheres to a particular communications protocol to pass through. Thus, the security afforded by the firewall is not compromised.
