MULTIMEDIA COMMUNICATION CONTROL UNIT AS A SECURE DEVICE FOR MULTIMEDIA COMMUNICATION BETWEEN LAN USERS AND OTHER NETWORK USERS
First Claim
1. A method for facilitating multimedia communication between a first endpoint on a first network secured by a firewall and a second endpoint on a second network external to the firewall, the method comprising:
- receiving, at a first logical port of a multimedia communications control unit, an indication of multimedia data streams between the first endpoint and the second endpoint, the multimedia communications control unit communicatively coupling the first and second network with a secure communication path that does not go through the firewall;
selecting a multimedia data stream received at the first logical port that conforms to a multimedia communications protocol;
providing the selected multimedia data stream to a common interface of the multimedia communications control unit, the common interface communicatively coupling the first logical port and a second logical port of the multimedia communications control unit via the secure communication path; and
initiating transfer of the selected conforming multimedia data streams via the second logical port to the second endpoint.

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

8. A multimedia communications control unit configured to facilitate multimedia communication to a first endpoint on a first network secured by a firewall, comprising:
-
a first logical port communicatively coupled to the first network; a second logical port communicatively coupled to a second network, the second network external to the firewall; and one or more processors, wherein the one or more processors are configured to; receive, at the second logical port, an indication of multimedia data streams between a second endpoint on the second network and the first endpoint on the first network, the multimedia communications control unit communicatively coupling the first and second network with a secure communication path that does not go through the firewall; select a multimedia data stream received at the second logical port that conforms to a multimedia communications protocol; provide the selected multimedia data stream to a common interface of the multimedia communications control unit, the common interface communicatively coupling the second logical port and the first logical port of the multimedia communications control unit; and initiate transfer of the selected multimedia data stream via the first logical port to the first endpoint via the secure communication path. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer readable medium comprising instructions stored thereon to configure a processor to facilitate multimedia communication between a first endpoint on a first network secured by a firewall and a second endpoint on a second network external to the firewall, the instructions that when executed by the processor cause the processor to:
-
receive, at a second logical port communicatively coupled to the second network, an indication of multimedia data streams between the second endpoint and the first endpoint; select a multimedia data stream received at the second logical port that conforms to a multimedia communications protocol; provide the selected multimedia data stream to a common interface communicatively coupling the second logical port and a first logical port, the first logical port communicatively coupled to the first network; and initiate transfer of the selected multimedia data stream through the first logical port to the first endpoint via a secure communication path that does not go through the firewall. - View Dependent Claims (16, 17, 18, 19, 20, 21)
