Enterprise Session Border Controller (E-SBC)

Enterprises, governments and call centers of all sizes are migrating their communications to all-IP, transitioning from PRI to SIP Trunks for PSTN connectivity, enabling mobility for remote users, and leveraging the cost benefits of cloud based UC services. At the enterprise network edge, issues like security and fraud, interoperability between different UC and PBX vendors, and service assurance from service providers are growing and require advanced session border controller (SBC) capabilities to ensure a seamless transformation to IP based real-time communications.


GENBAND provides a range of cost-effective enterprise SBC (E-SBC) solutions designed to meet the SIP multimedia session technical and business needs of enterprises of all sizes. These include a range of software centric VoIP SBCs available as software only or running on a Commercial Off the Shelf (COTS) appliance – on premise or in the cloud.
