Abstract
A decomposed H.323 border element is disclosed that is useful for providing an entry point from one or more H.323-based networks into a SIP-based VoIP network. In one embodiment, the signaling element of the BE is separated into a separate functional entity from the media control element to facilitate a single signaling entity controlling multiple media entities. In another embodiment, the security element of the border element is also separated from the media control element so that firewall and network address translation elements may be performed by a separate functional entity. In a further embodiment, the media transcoding element is separated from the media control element. In a final embodiment, the internetworking facility between the SIP and H.323 element is separate from the H.323 gatekeeper elements.
