Sonus ROI Benefits and Savings Calculator
This Microsoft Excel spreadsheet provides a three-year ROI calculator that helps enterprises calculate how much money they can save from VoIP initiatives such as SIP trunking, centralized dial plans, “take back and transfer” routing, decreased use of legacy TDM/H.323 resources and much more. The Calculator includes over 20 screens with data entry fields for dozens of different metrics (long-distance cost per minute, PRI trunk charges, equipment maintenance, etc.), so the more information you have, the more accurate your ROI model will be. (Translation: This is not a cookie-cutter ROI Calculator, but you’re not afraid to roll up your sleeves and dig into real numbers, are you?) The Calculator provides a summary at the end that presents total savings across all projected initiatives.
SIP-to-SIP: The Interop Dilemma (and How You Can Fix It)
With the proliferation of PBX and SBC solutions, SIP interoperability is a growing challenge for service providers and enterprises. This white paper explains the issues behind SIP interoperability and what network operators should look for in a SIP interoperability solution, such as industry certification, third-party validation and flexible methods for SIP normalization.
Heavy Reading: Network Modernization in the Era of All-IP Networks
Despite the availability of the next-gen solutions, many fixed and mobile operations still predominantly rely on decades-old TDM gear in their core networks. Replacement of these legacy networks represents a critical and necessary step to cost-effectively deliver IP broadband services, both now and in the future.
This white paper analyzes the drivers for TDM replacement, assesses the progress made to date, and presents a number of critical IP services use cases that provide the foundation for business cases. In addition, this white paper presents profiles of three network operators that are at various stages in TDM core network replacement, to provide an objective view of the steps and considerations inherent in defining an IP transformation strategy.
The Need for Active Quality Assurance in Carrier-Class VoIP Networks
In the pursuit of superior, carrier-class VoIP call quality, network operators should measure their network performance both in terms of Quality of Service (QoS) and Quality of Experience (QoE). VoIP operators have two methods for QoE metric generation: active call monitoring and passive call monitoring. Passive call monitoring analyzes existing call data in the network while active call monitoring simulates real-world VoIP calls to replicate end user call conditions. This white paper examines the need for a complemetary approach to QoE call monitoring, with specific emphasis placed on the new network requirements for active call monitoring.
Protecting Enterprise Call Centers From Voice-Based Attacks
Voice-based attacks are a real and growing threat to enterprises and government agencies. SBCs offer some protection, but are less effective against application-based attacks like TDoS and voice spam that target call centers and other customer services. These attacks can lower customer satisfaction, damage the company’s brand image, and cost the company millions in lost sales. To protect the voice-based applications that drive much of their business, enterprises need to implement an application-aware voice security solution. Sonus VoiceSentry is a sophisticated application-aware voice security solution. Designed by Sonus engineers to interoperate with Sonus’ industry-leading VoIP network elements, VoiceSentry protects mission-critical call centers while providing increased revenue potential, cost savings, improved security and improved customer satisfaction.

Transforming HD Voice into a truly global service: The Sonus® Unified HD Voice Solution
HD Voice is expected to revolutionize VoIP, both in the service provider and enterprise
markets. Clear and life-like reproduction of audio will lead to increased usage and additional
use cases for VoIP. The main impediment to mass adoption of HD technology, however, is
simply that the various HD Voice services, that use different HD Voice codecs, cannot
interoperate with each other. An HD solution, such as the one offered by Sonus, will help
bridge this divide and create a truly global HD Voice service.
Beyond the Border: Differentiating IPX Services with the Sonus® Network Border Switch
As all fixed and mobile networks migrate to IP to support the proliferation of IP applications, services, and devices, the role of IP Interconnect is quickly growing beyond basic border control. An IPX Provider can leverage its capabilities for value-added signaling interworking, media transcoding, routing, and addressing to support their customers’ service velocity, business growth, and service usage across disparate networks worldwide.
VoIP Encryption in the Enterprise
As enterprises shift more of their critical internal and external communications to a unified, IP-based voice/data network, they are increasing their network’s exposure to VoIP-based attacks. Meanwhile, the cost of not practicing secure VoIP communications is rising in the form of stricter government and industry regulations and the direct costs of lost confidential information, lost service, and lost credibility. With the trend toward real-time unified communications, the requirements of VoIP security will increase exponentially, placing added importance on solutions that deliver high scalability and high performance.
The Sonus NBS5200 provides enterprises with a cost-effective and scalable solution for VoIP security and encryption. With a unique architecture that divides security functions among multiple processors on a single chassis, the NBS5200 delivers the high-performance encryption and security that enterprises need to navigate the future of all-IP communications safely and securely.
The Evolution of SBCs
As IP networks evolve, demands on the SBC continue to increase, both in supported functionality and in performance requirements. This white paper discusses a few key areas where the next generation of SBCs will differentiate themselves from their predecessors.
Sonus® IMS Solution For Interconnect Providers - Enabling New Revenue Streams in a Competitive Marketplace
Interconnect providers have traditionally played the role of “invisible” middlemen, carrying voice and data traffic between the service providers that owned the end user relationship. In this central but limited role, interconnect providers have had limited access to the larger revenue pool of subscriber services. However, interconnect providers also occupy a unique and desirable position in the service flow because all interconnect traffic passes through them. To better leverage this position, Sonus Networks has created an innovative proposal that can increase the value of interconnect providers in the revenue chain by capitalizing on their position as middlemen.
