AudioCodes Mediant Software Enterprise Session Border Controller (E-SBC) is a member of the AudioCodes family of Enterprise Session Border Controllers. As a software-only session border controller solution, the Mediant Software E-SBC runs on commercial off-the-shelf servers, and enables connectivity and security between Enterprise and Service Providers' VoIP networks.
The Mediant Software E-SBC provides Perimeter Defense as a way of protecting enterprises from malicious VolP attacks; mediation for allowing the connection of any IP-PBX to any Service Provider; and Service Assurance for service quality and manageability. The Mediant Software E-SBC scales from tens to thousands of secured E-SBC sessions (exact capacity varies depending on server and functionality usage).
The Mediant Software E-SBC provides a perfect solution for security focused organizations such as contact centers, large data centers, hosted services and government institutions.
Why Enterprise Session Border Controller?
Session Border Controllers were originally deployed at the border of Service Provider core networks. Both enterprises and Service Providers have now realized the essential need of enterprisebased session border controllers, located at the customer premises for addressing the security, mediation and SLA requirements of the enterprise. The Mediant Software E-SBC provides an open and flexible architecture for all enterprise deployments, acting as the demarcation point between the enterprise and SIP Trunking providers, an enterprise and a hosted Unified Communications service provider, or an enterprise and other organizations for direct VoIP calling.
Vast Mediation Capabilities and Proven Interoperability
In a world of growing implementations of SIP flavors, enterprises and Services Providers alike must ensure interoperability for successful integration and service delivery. The Mediant Software E-SBC, includes comprehensive media security, and SIP normalization capabilities. As a direct evolution of the field-proven and highly interoperable AudioCodes E-SBC product family, the Mediant Software E-SBC provides unparalleled interoperability, enabling mediation between an extensive list of IP-PBXs, Unified Communications solutions and SIP Trunking providers.
High Availability and Survivability
The Mediant Software E-SBC supports high-availability configurations with reliable two box redundancy, ensuring no loss of active sessions during failure time.
SIP Trunking Solution
The Mediant Software E-SBC provides security, session mediation and service level assurance services, connecting the enterprise to multiple SlP 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 Software E-SBC monitors these User Agents, and resolves any NAT traversal issues they might face.
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 Software 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 Software E-SBC enables internal calls to continue uninterrupted.
Mediant Software 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 Software E-SBC offers Service Providers, who deliver hosted and managed communications services, a clear and easy-to-manage demarcation point, combining security, mediation services, and service level assurance.
Mediant Software E-SBC in Enterprise Networks
Enterprises are motivated to become more productive, efficient, and responsive to their internal users. The combination of secured voice services, standalone survivability, mediation services and service level assurance offered by the Mediant Software E-SBC ensures a high level of investment protection, cost optimization and support for the growing communications needs of enterprise users, whether at the head office, branch offices or on the road.
