The Mediant 3000 E-SBC provides Perimeter Defense as a way of protecting enterprises from malicious VoIP attacks; mediation for allowing the connection of any PBX and/or IP-PBX to any Service Provider; and Service Assurance for service quality and manageability. Designed for high capacity and high performance, the Mediant 3000 E-SBC is based on AudioCodes' VoIPerfect best-of-breed Media Gateway technology, scaling up to 1000 secured SBC VoIP sessions. The native implementation of SBC functions on the Mediant 3000 VoIP Media gateway platform provides a host of additional capabilities that are not possible with standalone SBC appliances, such as VoIP gateway and PSTN routing functionality. This enables enterprises to utilize the advantages of converged networks and eliminate the need for standalone appliances.

Why Enterprise Session Border Controllers?

Session Border Controllers were traditionally deployed at the border of service provider core networks. Both Enterprises and Service Providers have now realized the essential need of enterprise-based session border controllers, located at the customer premises for addressing the security, mediation and SLA requirements of the Enterprise. The Mediant 3000 E-SBC provides an open and flexible architecture for all Enterprise deployments, acting as the demarcation point between an Enterprise and a SIP Trunking provider, an enterprise and a hosted Unified Communication service provider or an enterprise and other organizations for direct VoIP calling.

Integrated PSTN connectivity

Customers can safely and transparently migrate from traditional PSTN to SIP Trunking with the Mediant 3000 E-SBC, a cost-effective method of increasing the value of their data network, while also protecting their investment in legacy PBX equipment. In addition to E1/T1 interfaces, the Mediant 3000 E-SBC supports high-density PSTN interfaces, such as T3, STM-1 and OC3.

Vast mediation capabilities and proven interoperability

In a world of growing choices of voice coders and SIP flavors, enterprises and services providers alike must ensure interoperability for successful integration and service delivery. The Mediant 3000 E-SBC, with its extensive media processing capabilities, supports a wide range of voice coders with the ability of transcoding between narrowband and wideband voice coders, including SIP normalization, fax handling, gain control and numerous additional media processing features. As a direct evolution of the field-proven and highly interoperable Mediant 3000 VoIP media gateway, the Mediant 3000 E-SBC provides unparalleled interoperability, enabling mediation between an extensive list of IP and TDM PBXs and SIP Trunking providers.

High Availability and survivability

The Mediant 3000 E-SBC supports high-availability configurations with reliable, “1+1” redundancy of all system components, ensuring no loss of active sessions during failure time. The Mediant 3000 E-SBC is equipped with PSTN interfaces that can also provide local survivability via PSTN fallback connectivity (including E911), when the WAN is unavailable.

Applications

Sip Trunking Solution

Using the Mediant 3000 E-SBC, enterprise customers can seamlessly migrate from legacy PSTN connectivity to cost-effective SIP Trunking Services. The Mediant 3000 provides security, session mediation and service level assurance services, connecting the enterprise to multiple SIP Trunking providers, while maintaining interoperability and manageability.

Contact Center Solution

Contact Centers place the SIP Application Server in the LAN, with SIP User Agents deployed remotely across the WAN. The Mediant 3000 E-SBC monitors these User Agents, and resolves any NAT traversal issues they might face. In addition, with its vast media processing features such as Voice Activity Detection, Answering Machine, Call Progress Tone, and DTMF detections, the Mediant 3000 E-SBC provides support for outbound calling campaigns, utilizing the same hardware resources.

Hosted Centrex Solution

IP Centrex solutions rely on VoIP technology, whose implementation may present significant challenges, especially to businesses without prior VoIP experience. One of the challenges is service continuity during WAN outages. The Mediant 3000 E-SBC, with its Stand Alone Survivability feature, is able to monitor registrations to the SIP Proxy, so that if connectivity is lost the Mediant 3000 E-SBC can continue to serve in both internal and external calling capacities.

Mediant 3000 E-SBC in Service Provider Networks

As Enterprises strive to control their communication operating and equipment costs, outsourcing Voice and Data infrastructure to a Service Provider is becoming an attractive option. The Mediant 3000 E-SBC offers Service Providers, who are delivering hosted and managed communication services, a clear and easy-to-manage demarcation point, combining Security, Mediation Services, and Service Level Assurance.

Mediant 3000 E-SBC in Enterprise Networks

Enterprises are motivated to become more productive, efficient, and responsive to their internal users. The convergence of secured voice services, Stand Alone Survivability, Mediation Services and Service Level Assurance, ensures a high level of investment protection, cost-optimization and support for the growing communication needs of the Enterprise. The high-density Mediant 3000 E-SBC is a well-suited platform for converging VoIP Gateways and Session Border Controllers, thereby improving the enterprise headquarters’ service level for local, branch and mobile users.
