QUANTiX QFlex Solves SIP Trunking Interoperability Challenge

August 20, 2014

As SIP trunking extends from early adopters to businesses of all types, from small firms to large enterprises, network operators are facing interoperability challenges when it comes to connecting IP-PBX systems from different vendors.

GENBAND hopes to ease those challenges with its QUANTiX QFlex session border controller (SBC). The software-based SBC resolves the challenge of interoperability by providing a demarcation point protecting both the service provider SIP Trunks and enterprise local network and coming with a number of adapters that handle interoperability issues.

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 capabilities, according to the company.

What makes the solution unique, however, is that QFlex resolves multi-vendor interoperability issues by using pre-loaded adaptors with profiles for all major IP-PBX vendors, core session border controllers and application server platforms.

“This simplifies and reduces the time-to-market for service providers to deploy SIP Trunking services, cutting the interoperability time from months to weeks,” according to GENBAND.

QFlex enables enterprises to use supplementary services such as call forwarding, transfer, and music-on-hold in a multi-vendor PBX environment, across different branch offices, and it also enables 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.

The solution scales from 1 to 1000 simultaneous sessions, and it supports a pooled license model that allows sharing of session capacity across multiple QFlex appliances or software instances.

As a full-feature SBC, The QFlex also offers trunk-specific call treatment policies, call admission control, emergency number prioritization, quality of service settings, and statistics, load balancing of traffic both on LAN and WAN sides, digit Manipulation, SIP error code manipulation and other features.

Interoperability might be a challenge for some operators, but it doesn’t have to be.
