Core SBCs – Ready to Meet the Demand for Direct Routing

Ribbon’s core SBCs, including the Software Edition (SBC SWe), SBC 5400 and SBC 7000, are designed for the heart of service provider networks. They are architected for high availability, scalability, and are seamless integrated with

Ribbon’s centralized routing and policy engine, PSX, to streamline network-wide routing and session management. Ribbon’s core SBCs are also integrated with Ribbon Analytics and Ribbon’s Identity Assurance solutions so service providers can proactively manage the security and integrity of their overall network and individual calls.

Ribbon’s SBC SWe, SBC 5400 and SBC 7000 are all Microsoft certified and able to support tens of thousands of concurrent Direct Routing sessions per instance, making them an extremely cost-effective way to deliver SIP trunks to Microsoft Teams deployments.

Many Microsoft Teams users are foregoing traditional SIP Trunking deployment models that delivered SIP trunks to the customer’s premises. Instead, they are opting for their SIP trunks to terminate in the Microsoft Azure Cloud, eliminating any reliability issues tied to the last mile. In time, this will likely lead to service provider deployments of hundreds of thousands of sessions between their own networks and Azure. That will make the resiliency and scale of these connections critical. The carrier scale, multi-tenant capabilities and configuration flexibility of Ribbon’s SBCs make them the ideal choice for this high-volume deployment model.


Virtualized Software for the Core

Enable Microsoft Direct Routing from your Network or the Public Cloud

Ribbon's SBC Software Edition (SWe) uses identical software to the award-winning SBC 5000 series and SBC 7000, minus the hardware. Ribbon’s SBC SWe delivers the same carrier-class redundancy to ensure service continuity; is deployable on multiple cloud environments and provides industry-leading media transcoding using GPUs to scale for high-density transcoding, including Microsoft’s SILK codec.

The cloud native SBC SWe, assures service providers that they will be able to deliver secure real-time communications on almost any private or public cloud environment without compromising scale and performance. It is also available on AWS Marketplace and as an AWS Quick Start.

Microsoft Operator Connect Integration

Microsoft Operator Connect is a next-generation cloud-to-cloud interconnect solution. Service Providers can combine their SIP Trunking services with Microsoft 365 workflow APIs to make it easy for enterprises 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; Ribbon is working with Microsoft and many of the Service Providers rolling out this new service.

  • Service Providers connect to the Microsoft 365 cloud using their peering SBCs
  • Operator Connect provides integration tools (APIs) so carriers can leverage the Microsoft 365 portal to engage with new customers and deploy SIP trunks (DIDs/DDIs)

Intelligent Edge Hardware – Monetize the Last Mile

Ribbon’s Intelligent Edge™ hardware offers an intelligent demarcation point on the customer premises along with best in-class eSBC services and multiple options for FXO and FXS (analog and digital) connectivity to simplify migrations to Teams.

Even with the very best core network, there are still advantages to an intelligent device deployed at the edge of the enterprise network. Service providers can leverage the EdgeView Service Control Center to manage thousands of Ribbon appliances deployed at the enterprise edge. Ribbon’s eSBCs cost effectively manage the last mile, reduce tech dispatches and shorten CSR trouble shooting time. Providers can further accelerate EdgeMarc appliance deployments using EdgeView’s Zero Touch Provisioning.

The Ribbon SBC 1000 and SBC 2000 give service providers a compelling resiliency offer by supporting Microsoft’s Survivable Branch Appliance (SBA). The SBA capability gives users a back-up plan for outbound calling if the Azure Cloud become unreachable. The EdgeMarc 6000 includes LTE back-up in case of a wired WAN failure.

Virtualized Software and Public Cloud for the Edge

Enable Direct Routing for Microsoft Teams from the Azure Cloud or Amazon Web Services (AWS)

Ribbon’s Session Border Controller, Software Edition Lite (SBC SWe Lite), deploys in the Azure or AWS cloud as well as on Hyper-V, VMWare and KVM. Regardless of the deployment choice, SBC SWE lite provides a secure bridge between a provider’s SIP trunks and an enterprise’s Teams deployment. It’s an ideal solution for organizations that want to bring their SIP trunks directly into a public or private cloud. Service providers can easily deliver a managed SBC service (including centralized management via the EdgeView Service control Center) by hosting SBC SWE Lite in their own network or the public cloud.

There is no dedicated SBC hardware to deploy or manage, as everything is in the public or private cloud. The solution is operational in minutes and can scale up or down as needed. Ribbon’s SBC software is designed for compute efficiency. In fact, a small business can be supported with a single Standard_B1ms virtual machine instance on Azure or a Burstable t3.small virtual machine instance on AWS.

Ribbon Advantages Include:

  • Microsoft-certified including optional services such as Local Media Optimization and e911
  • Robust security to keep bad actors out the network and prevent service disruptions
  • Full media services including SILK and OPUS transcoding
  • Easy Configuration Wizard speeds deployments and reduces configuration errors, Watch the Video

Tools to Help Enterprises Migrate to Teams

Service providers are already fielding questions from organizations looking for options to move all or some of their employees off a traditional PBX to Teams. Microsoft Teams doesn’t inherently offer any specific tools for migrating 3rd party PBXs to Teams. However, Ribbon SBCs can make migration easier so you can retain existing customers. Not only does this reduce churn, it reduces comparative shopping that could drive down your SIP trunk prices and margins.

Most Ribbon SBCs offer SIP Forking to provide simultaneous ringing of the legacy PBX and Teams. In addition, our SBC’s dial plans can redirect calls, so users don’t need to be routing experts to connect with co-workers on another system.

Ribbon’s SBC 1000 and SBC 2000 as well as the EdgeMarc 2900 series, 4800 series, 6000 series and 7000 series provide FXO and FXS ports (both analog and digital) to simplify connectivity to existing devices. These may include legacy PBXs, contact centers, elevator phones, emergency calling boxes, door phones, common analog phones and more.

In addition, Ribbon Connect for Microsoft Direct Routing offers another level of integration by registering as a soft client off the legacy PBX. This station-side migration option creates tighter integration between the legacy environment and the newer Teams environment. It also reuses existing trunking so organizations don’t need to shop for PSTN services. It can also be activated on a per seat basis so organizations can choose to offer Teams calling to a select group of users.


Microsoft Survivable Branch Appliance Support

Enable Teams users to make and receive calls to/from the public telephone network if Microsoft 365 becomes unreachable. Microsoft’s Survivable Branch Appliance (SBA) capabilities are available for the SBC 1000 and SBC 2000 (Server Module required) as well as offered as fully virtualized software in concert with the SBC SWe Lite. Ribbon enterprise SBCs already provide support for resilient WAN connections, adding Microsoft’s SBA services provide the next level of resiliency by assuring that users can still make and receive calls, in the event of a WAN or cloud outage. It is an ideal way for service providers to add value to a managed Microsoft Teams offer. Microsoft SBA services are tightly integrated into the enterprise SBC’s Easy Configuration Wizard, making set-up and administration as simple as point and click. Ribbon eliminates any SBA related command line administration or stand-alone security certificate management.

The SBC 1000 and 2000 also support connectivity to traditional analog and digital circuits (POTS, BRI, T1/E1 circuits) for an additional level of redundancy, beyond SIP trunk connectivity. Learn more by downloading the SBA datasheet.

Survivable Branch Appliance (SBA) for Microsoft Teams

Use Ribbon Connect to Jump Start Teams Direct Routing

Ribbon understands that service providers may recognize the need to get to market with a Direct Routing offer but are constrained by the investments required. Ribbon Connect for Microsoft Teams Direct Routing provides a cloud-based SBC as a service as well as turn-key web portal for administration. Providers can extend the value of their existing SIP trunks to deliver a fully certified Microsoft Direct Routing solution immediately, without CAPEX investments.

Ribbon Connect for Microsoft Teams Direct Routing is delivered on a per-user (per seat) basis. If an organization has 20 users that need Teams calling services, a provider sells that organization 20 seats of Ribbon Connect, from the Ribbon cloud. Providers can co-brand or completely rebrand the offer. Ribbon Connect can easily accommodate hundreds or thousands of seats. The solution scales up to match increasing use and scales down as business needs or seasonality dictates. There are no contract minimums or long-term contacts lock-ins.

CSPs that are concerned that their staff can’t get up to speed on Microsoft Direct Routing can take solace in knowing that Ribbon Connect is administer via intuitive web-based menus, just add the users’ credentials. Ribbon Connect can automatically make configuration updates in Teams, set-up Session Border Controller services and even integrate with an existing IP-PBX or Cloud UC service.
