Session Border Controllers for Service Providers

What makes Ribbon SBCs stand apart from the competition? Maybe it’s the fact that the world’s most demanding service providers have trusted Ribbon to deliver secure, high-quality SIP communications for more than 20 years. Maybe it’s the peace of mind that comes from independent testing that shows that Ribbon SBCs can thwart the most challenging denial of service attacks without impacting call traffic. Or, maybe it’s because we offer more deployment choices with unique SBC models that offer the right solutions for small businesses as well as the best performance and security for Tier 1 service providers. It could also be the knowledge that Ribbon’s software-based solutions have the same robust performance and scale as its hardware-based products. In the end, it likely comes down to something simple - Ribbon SBCs simply work.

Ribbon SBCs are just one piece of Ribbon’s real-time communications security practice. They work in concert with Ribbon’s Analytics portfolio to provide operational efficiencies and proactive security services. Interworking between Ribbon SBCs and our Analytics Security applications make it possible to more effectively respond to real-time communications cyberattacks, fraud attempts and network quality incidents than competitors with standalone solutions.

Of course, in addition to security, SBCs play a number of critical roles in service provider networks. Ribbon SBCs are often deployed along with Ribbon’s centralized policy and routing solutions (PSX) to enable highly efficient and  scalable network policy and routing control. Service providers can institute a policy change and see it start to cascade across a world-wide network in minutes. This deployment model accelerates responses to threats and dramatically reduces operational costs compared to traditional solutions. It’s no wonder the leading IPX providers around the globe rely on Ribbon solutions.

Service Provider Core Network

Ribbon's family of next-generation session border controllers (SBCs) provide robust security, simplified interoperability, advanced session management, and carrier-grade reliability for fixed, mobile, cable, and wholesale service providers. Ribbon's SBCs offer powerful deployment flexibility that meets or exceeds the demanding levels of security and service quality for applications such as SIP trunking (including Microsoft Teams Direct Routing), Unified Communications, Network-Network Interconnection, VoLTE, VoWiFi, and RCS. Ribbon SBCs deliver network security, routing and policy management, overload controls, SIP normalization along with IPv4-IPv6 interworking, and robust media transcoding. They also deliver support for STIR (Secure Telephone Identity Revisited) and SHAKEN (Signature-based Handling of Asserted information using toKENs) standards for caller authentication.

Public Cloud and Virtualized Software

Deploying unified communications, conferencing, collaboration or contact centers applications on a public cloud (AWS, GCP, Azure) is becoming commonplace. Until recently, many of the SBCs available in the public cloud didn’t deliver the security, scalability, reliability or functionality required to deliver carrier-grade services. Ribbon’s virtual, cloud-native SBC Software Edition (SWe) can meet security and interworking needs today and in the future.

Network Functions Virtualization (NFV)

Many service providers are seeking to deploy NFV in their private cloud environments.  Ribbon virtual network functions (VNFs) are designed as cloud native microservices that ensure automation, orchestration, elasticity and scalability in geo-distributed, multi-cloud, core and edge topologies. Ribbon’s SBC SWe is part of a suite of OpenStack-based VNFs developed to align with both ETSI and ONAP. Best of all, the SBC SWe shares its software code base with the SBC 5000 and 7000 portfolios, making it is one of the most trusted security solutions on the planet.

STIR/SHAKEN and Identity Assurance

Ribbon’s Core SBC portfolio plays an important role as an enabler for our customer’s implementation of STIR/SHAKEN. SBCs interwork with call controllers and the Ribbon PSX to handle caller authentication or verification request queries and update the information in the SIP message per the response. In addition, SBC CDRs can be fed into Ribbon Analytics to assist in determining potential robocall or fraud call attempts. Our STIR/SHAKEN SBCs:

Turnkey Hardware Platforms

Ribbon SBC platforms are known for their performance and scale, even while under attack. Ribbon 5000, 7000 and SWe SBCs share a common code base that makes them easier for organizations to operationalize and maintain. Our SBCs are designed to support emerging services such as high definition (HD) voice and video, Voice over Long-Term Evolution (VoLTE) and Rich Communications Services (RCS), without sacrificing performance or security. In fact, the SBC 7000 touts the industry’s highest scale – up to 150,000 sessions with fully enabled security, media and transcoding features. It supports nearly 10 times more Secure Real-Time Transport Protocol (SRTP) sessions than any other SBC on the market. Review all the hardware-based platforms below:

Microsoft Teams Direct Routing

Teams is the fastest growing business application in the Microsoft’s history. Service providers can tap into this success by being the provider of choice for connecting SIP trunks to the Microsoft Phone System through Direct Routing.

Securing and ensuring interoperability for SIP trunking, Ribbon’s core SBCs deliver multi-tenancy, scalability and high-availability that is required to provide cost-effective connectivity to Microsoft Teams customers, including the direct connections between a service provider’s network and Microsoft Azure.

Ribbon’s extensive portfolio of Microsoft-certified session border controllers, coupled with decades of experience building session border controllers for SIP trunking, make Ribbon the right solution for service providers to deliver market-leading Direct Routing services to new and existing business customers.

Microsoft Operator Connect

Microsoft Operator Connect is next generation cloud-to-cloud interconnect solution that tightens the integration between service providers and Microsoft Teams. Designed to simplify the Teams customer experience, service providers can combine their SIP Trunking services with Microsoft 365 workflow APIs to make it easy for enterprise to acquire and deploy PSTN calling services for Teams. Enterprises can configure users for Teams calling and at the same time buy and assign DIDs/DDIs from their preferred service provider.

Ribbon SBCs are fully compatible with Operator Connect and Ribbon is working with Microsoft and many of the service providers rolling out this new service.

  • Service providers connecting to the Microsoft 365 cloud using their peering SBCs
  • Operator Connect providing integration tools (APIs) to automate the interaction between service provider and Microsoft, enabling carriers to sell and deploy SIP trunks (DIDs/DDIs) from inside of the Microsoft 365 portal

Service Provider Intelligent Edge

The dramatic rise in hosted and cloud-based services creates opportunities for service providers to deliver high-value services. However, it also creates new challenges in terms of deployment and management. As businesses move their communication services to the cloud, they expect service providers to proactively manage and secure those services. Ribbon’s Intelligent Edge™ portfolio is designed to meet the demanding needs of service providers looking to deploy Unified Communications and SIP Trunking, including Microsoft Teams Direct Routing, with a high degree of security and quality. Ribbon provides both hardware and software-based solutions. Ribbon hardware can act as full-fledged service demarcation devices for enterprise edge networks and provided analog or digital ports to simplify migration of legacy PBXs, call centers and analog devices. In addition Ribbon offers software only solutions that can be deployed on virtualized hardware or the public cloud (in Azure and AWS). Ribbon’s EdgeView Service Control Center provides centralized management and zero touch provisioning. It’s no wonder that Tier 1 service Providers have over ¼ million EdgeMarcs deployed.

Microsoft Teams Direct Routing

Many organizations are already using Teams for video conferencing, collaboration, file sharing and chat. Microsoft Phone System Direct Routing allows organizations to connect to external phone lines and use Teams as an office phone system. Direct Routing requires a Microsoft certified Session Border Controller (SBC) to connect Teams to a communications service provider.

As a long-time partner of Microsoft, Ribbon’s Intelligent Edge SBCs are certified to secure these connections and assure interoperability so organizations can select from hundreds of service providers across the globe. Each service provider has multiple options to provide the required SBC, including both software and hardware solutions that can be on the customer’s premises or in private or public cloud.
