Kagoor Networks has enhanced its VoiceFlow session border control solutions with new functionality that enables direct media flow between endpoints residing in a customer LAN behind a local data firewall/NAT device and gateways residing in the wide area network (WAN). This eliminates unnecessary routing of the media through the session border controller(s), thereby reducing cost, and latency and improving network scalability.
Using Kagoor’s network-hosted NAT traversal application, the VoiceFlow session border controller automatically recognizes calls between VoIP endpoints (IP telephones, Integrated Access Devices, etc.) on the same LAN and after initial call setup, instructs the endpoints to send media directly to each other. In this application, XpressPath operates with SIP, MGCP and H.323 NAT traversal applications.
The second XpressPath function addresses calls between VoIP endpoints on a LAN and a media gateway in the WAN. In this case, a VoIP endpoint is located behind a NAT/firewall and is served by the VoiceFlow network-hosted NAT traversal application. After determining that the call is an off-net call to the PSTN, VoiceFlow instructs the VoIP endpoint and the media gateway to exchange media directly. This conserves bandwidth and reduces latency, since the media does not have to return to the VoiceFlow and cross the WAN multiple times to reach the gateway destination.
