ISN Telcom Selects Kagoor's Session Border Controllers

ISN Telcom, the Miami based CLEC, has deployed Kagoor’s VoiceFlow 1000 session border controllers for its ipFONE VoIP service, which offer unlimited calls to Latin America in addition to the United States, and Canada for a single monthly fee. Kagoor’s session border controllers provide network protection and security for ISN’s VoIP network. Kagoor’s network protection applications include topology hiding, intrusion prevention, call admission control, and protection from denial of service (DoS) attacks. Kagoor also provides its hosted NAT traversal solution, which permits incoming VoIP calls to securely pass through firewalls. With the VoiceFlow network-hosted NAT traversal solution, ISN delivers its customers VoIP service without adding additional premises equipment.

Kagoor’s VoiceFlow fully supports all major VoIP protocols (SIP, H.323, MGCP).

The Evolution of Session Border Controllers Session border controllers have matured to play an essential role in delivering secure and seamless VoIP service. Most VoIP has been deployed in “islands”, either within enterprises deploying VoIP on a LAN or by a carrier using it for its internal network transport. In both cases, the VoIP traffic terminates at a gateway and is converted to PSTN as it leaves the enterprise or the carrier’s network. Session border controllers (SBCs) were designed to connect these islands and create an end-to-end VoIP network
