Session Border Controllers resolve the peering, latency, quality of service, capacity and control issues preventing widespread commercial deployment of VoIP. The SBC is a transparent addition to existing VoIP networks that enable carriers and service providers to fully realize PSTN parity - resulting in a reduction of costs and increased revenue through the interconnection of VoIP islands. Several current market drivers point to the increasing demand for IP services that can only become a reality with a native IP interconnection. VoIP networks are typically built as “island networks” due to complexities associated with IP interconnection or peering (such as
address overlap and security firewalls). The lack of scalability in current VoIP deployments is compounded by the lack of performance parity with the PSTN. Many indicators include the tremendous growth of IP PBXs and the adoption of VoIP and SIP-based products. nCite SBCs support three main application areas for wireline and wireless networks: Residential, Carrier to Carrier Peering and Enterprise.
nCite integrates both signaling and media in a single platform to securely and reliably deliver VoIP applications: voice, video and multimedia sessions across IP network borders. The nCite's hardware based platform ensures long term performance without forklift upgrades enabling true investment protection.
