Sonus Networks, Inc. announced that the Sonus SBC 1000 and SBC 2000 Session Border Controllers (SBCs) are certified for deployment with TalkTalk Business' Session Initiation Protocol (SIP) trunking services and Microsoft Lync Server 2013. SIP trunking solutions from TalkTalk Business allow enterprises to reduce capital expenditures by eliminating the need for equipment changeover or disruption of service, so legacy network investments are preserved; and reduce overhead costs associated with operating and maintaining multiple service-specific access lines. A Microsoft Gold Communications Partner, Sonus helps enterprises optimize Microsoft Lync voice deployments by securing SIP trunking services at the network border and providing a more seamless flow of SIP-based, multi-vendor media for advanced real-time applications like Unified Communications (UC). Access to UC applications such as instant messaging (IM), collaboration, conferencing and voice empowers enterprises to communicate in the most efficient and cost-effective ways -- whenever and wherever. TalkTalk Business' SIP trunking solution offers seamless integration, allowing the full range of voice call features to be used across an enterprise. The SIP trunking service can help enterprises save up to 50% on business phone bills and extend advanced communication features over IP to employees in all offices, whether a main site, a branch office or a remote location. Sonus SBCs serve as a foundational access technology to enable customers to unify disparate UC architectures across an enterprise. The Sonus portfolio provides the industry's only end-to-end SBC solution delivering SIP-enabled applications from the service provider to enterprise headquarters to the branch office.

Sonus Networks, Inc. announced significant software and hardware enhancements to its session border controller (SBC) portfolio, further enabling service providers and enterprises to simplify network design, reduce costs and effectively deploy advanced communications features to support their Unified Communications (UC) environments. New SBC portfolio offerings - including a new modular platform design, increased support for media services and wireless branch office survivability for Microsoft Lync - extend Sonus' technology leadership in the SBC market. Sonus' SBC portfolio serves as a foundational access technology to enable secure access to SIP trunking and unify disparate UC architectures across an enterprise. SIP trunking and the move to Voice over Internet Protocol (VoIP) can generally reduce traditional enterprise telecom bills by up to 50%. The Sonus portfolio provides the only end-to-end SBC solution portfolio delivering SIP-enabled applications from the service provider to enterprise headquarters to the branch office. As part of its ongoing commitment to customer deployment flexibility, Sonus is introducing two new modular platforms - the SBC 5110 and SBC 5210 Session Border Controllers -- to its service provider and enterprise portfolio. The platforms are built on the same proven hardware architecture and software as the SBC 5100 and SBC 5200 Session Border Controllers. As part of the product evolution, the SBC 5110 and SBC 5210 adopt a modular design that allows customers to install up to four digital signal processor (DSP) cards and is field upgradeable as network demands change. To go with the new modular platforms, Sonus is also delivering new DSP cards: the DSP20 and DSP25. These new cards, together with the new platforms, provide a substantial increase in DSP system capacity, giving customers greater support for border-based media control and services. The Sonus SBC 5110 and SBC 5210 -- as well as the DSP20 and DSP25 cards -- are available for immediate order and feature a new version of software which is consistent across the complete Sonus SBC 5000 Series. The new release 3.1 software delivers nearly 100 feature enhancements across the entire SBC 5000 Series, including: comprehensive media interworking; call recording for contact center, regulatory compliance, and security applications; expanded transcoding support for G722.1 for Polycom high definition voice; and DTMF and fax enhancements; bandwidth-based call admission control (CAC) to assure voice quality and simplify management; support for Proxy Call Session Control Function (P-CSCF) to enable the SBC 5000 Series to act as an access device bridging endpoints into the IP Multimedia Subsystem (IMS) core; and increased security and management capabilities, such as improved call detail record capabilities (CDR) and expanded alarms and notifications. The enhanced SBA functionality is available for immediate order on the SBC 1000 and SBC 2000 as part of software release 3.1. Additional software enhancements enabled by this release include: improved fax interworking; G.711 to T.38 transcoding for transmitting fax over SIP trunks and support for fallback to voice from T.38 fax; and support for Reason Header to improve user experience so that call notifications on Lync are not missed when a call is answered on another device.
