Cloud or Virtual Machine Deployment

Easily deploy Ribbon SBC software in multiple virtual environments

Ribbon’s Session Border Controller, Software Edition Edge (SBC SWe Edge) operates natively in the Azure and AWS Cloud as well as on virtual machine platforms including Microsoft Hyper-V, VMware, and Linux KVM. In minutes, an organization can deploy a Ribbon SBC to enable Teams Direct Routing, Zomm Phone BYOC, or to connect almost any other cloud UC or contact center service to a telecom provider. Organizations get the same ease of use and robust security services without having to deploy any hardware. And, since it’s deployed in virtual environments, it can scale up or down as needed. Ribbon even offers a 30-day trial license so your organization can try it out.

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 delivered as fully virtualized software in concert with the SBC SWe Edge. Microsoft’s SBA services provide organizations an additional level of resiliency and peace of mind that calling services can be preserved if the cloud becomes unreachable. Microsoft SBA services are tightly integrated into the SBC SWe Edge’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. Learn more by downloading the SBA datasheet.

Zoom Phone Local Survivability - ZPLS

Ribbon SBCs are certified to work in concert with Zoom Phone Local Survivability Software (ZPLS). Zoom’s ZPLS software is deployed on-site to provide basic calling services, if the Zoom cloud is unreachable. The software works in concert with a Ribbon SBC to provide local access to telecom services (PSTN) – via locally terminated SIP trunks or using traditional analog/digital PSTN lines. The ZPLS software is deployed on a virtual server and remotely managed by Zoom to make deployment easy. If the Zoom cloud is unavailable, ZPLS enables intra-site calling (including directory-based calling). Ribbon’s SBCs add PSTN access so users can place and receive calls to/from anywhere – keeping employees connected and customers happy. It’s an ideal solution to assure emergency services access at schools, healthcare facilities, or any other mission-critical organization. Learn more from our Blog Post

Hardware, Software or Cloud

Visitors may notice the similarities between the SBC SWe Edge, SBC CNe Edge, SBC 1000 and SBC 2000, we hope so. Ribbon uses the same core software for these products so our customers can easily choose the size and deployment model that fits their environment. Each product delivers the same robust security services, ease of deployment, and media management capabilities. The SBC SWe Edge includes the option to deploy on a virtualized platform or the cloud, the SBC CNe Edge is exclusively for the cloud, while the SBC 1000 and SBC 2000 provide options for physical interfaces (FXO/FWs, T1/E1, etc.) for device or PBX/ contact center migrations.

Hear the Ribbon Difference

As a security element, SBCs inherently sit in the middle of the media path between the telecom provider and the phones or soft clients. Ribbon’s SBC SWe Edge uses that position to enhance media quality and manage interoperability between the endpoints and the telecom providers. Ribbon leverages our decades of experience building many of the world’s largest communications networks to deliver better sounding conversations. Our software better mitigates common voice quality issues our competitors typically leave to chance.

The SBC SWe Edge enhances:

  • Media Transcoding (to ensure device/ service interoperability)
  • Concealment of Network Jitter (to mitigate network anomalies)
  • Comfort Noise (to make conversation sound more natural)
  • Music on Hold fidelity (we still can’t guarantee you’ll like the tune)
