“Enterprise SBC with Proven Interoperability”
Today’s businesses have to compete in an increasingly globalized
marketplace. Round the clock operations, distributed locations –
nationally and internationally, and a growing remote and mobile
workforce are requiring businesses to adopt technologies that
improve productivity and reduce operational costs. Businesses are
looking to IP-enable their communications infrastructure and leverage
their investments to converge voice and data networks. Businesses
and enterprises of all sizes - including small offices, government
organizations, universities, and contact centers - are migrating to IPenabled PBXs and replacing PRI links with SIP Trunks.
SIP Trunking and Unified Communications adoption is steadily
growing, creating security and interoperability challenges between the
service provider’s network and the enterprise’s network. GENBAND’s
QUANTiX QFlex is a software based enterprise Session Border
Controller (eSBC) that resolves these challenges by providing a
demarcation point protecting both the service provider SIP Trunks and
enterprise local network and offering proven interoperability with a
wide variety of IP PBXs and other network elements.
Optimized for small to mid-sized businesses and branch offices of
mid-to-large enterprises, the QUANTiX QFlex serves the role of a
Back-to-Back User Agent (B2BUA) at the enterprise network edge and
provides security, topology hiding, SIP ALG, NAT/PAT translation,
IP PBX interoperability and remote monitoring and management
The QFlex eSBC uses a unique approach to solve multi-vendor
interoperability issues by utilizing pre-loaded adaptors with profiles
built for all major IP PBX vendors, core session border controllers,
and Application server platforms. The QFlex eSBC allows service
providers to deploy an enterprise IP PBX with specific profile towards
the LAN and to have a SIP Trunk provider-specific profile on the WAN
interface. With support for a wide range of IP PBX vendors and
release version profiles, QFlex enables service providers to reduce
time to market by cutting interoperability time from months to weeks or
days and offering SIP Trunk services to a broader market.
This unique interoperability approach helps service providers and
enterprises use supplementary services such as call forwarding,
transfer, and music on hold in a multi-vendor IP PBX environment,
across different branch offices.
The QUANTiX QFlex eSBC is ideal for securing SIP Trunks from service
providers, assuring multi-vendor IP PBX interoperability for branch office
consolidation over MPLS networks, routing traffic in IP-enabled call
centers, and allowing remote users and satellite offices to securely
connect to corporate IP communication systems.

Centralized Management System
QFlex is complemented with a fully redundant web- based
centralized element management system, designed to simplify the
deployment and management of large numbers of QFlex eSBCs.
Some of the capabilities of this system include:
• Auto-discovery of QFlex with template-driven configuration
• Management of shared license pools across multiple QFlex
• Centralized repository of eSBC configurations
• Remote management, diagnostics, trouble shooting and
