The Ribbon Session Border Controller 1000 (SBC 1000) is an ideal security and interoperability solution for small businesses and branch offices. The SBC 1000 delivers:

  • VoIP Security (topology hiding, encryption, protection against Denial of Service attacks, and more)
  • Interoperability with leading PBXs, cloud UC services, cloud contact centers, SIP endpoints, and SIP trunking providers
  • Certified for Microsoft Teams Direct Routing, Zoom Phone BYOC, Webex Local Gateway & Google Voice SIP Link
  • Local site survivability services, including Microsoft SBA
  • Gateway for traditional interfaces including analog devices, analog lines, BRI, and PRI
  • Advanced call routing features such as Active Directory/LDAP server routing integration and onboard call forking


The SBC 1000 is the smallest member of Ribbon’s SBC family but don’t let its diminutive size fool you. It uses the same powerful software deployed in larger models and cloud-based offers. That’s one reason the SBC 1000 has been independently verified to deliver complete protection and performance during severe security attacks. The SBC 1000 is ideal for organizations seeking to protect SIP trunks or cloud UC services, including Microsoft Teams and Zoom Phone. It also provides tools and physical interfaces to ease migrations from legacy PBXs and key systems. Organizations that need to connect traditional analog phones (such as cordless phones, elevator phones, door phones, fax machines, etc.) or want to connect local phone lines (for local dial tone or emergency/ fail-over calling) will appreciate the SBC 1000’s FXO/FXS ports.

The SBC 1000’s intuitive web interface, including multiple ready-to-use configuration parameters, makes it easy for small businesses and branch offices to get in-service; no Ph.D. in SBC is required. License-based sessions and port expansion eliminate the need for a truck roll and/or an on-site technician.

The Ribbon SBC 1000 is certified for Direct Routing with Microsoft Teams, Zoom Phone BYOC, Cisco Webex Local Gateway, Google Voice SIP Link, and has been deployed with nearly every popular cloud service or premises-based communications equipment. It also features built-in survivability for Microsoft Teams, Yealink, Poly, Cisco/BroadSoft, and other SIP/TDM/FXx clients, so calls go through even if the Wide Area Network (WAN) goes down.

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) capability is available for the SBC 1000 (Server Module required). The SBC 1000 already provides support for resilient WAN connections, adding Microsoft’s SBA services provides the next level of resiliency by assuring that users can still make and receive calls, in the event of a WAN or cloud outage. Microsoft SBA services are tightly integrated into the SBC 1000’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 also supports traditional analog and digital circuits (POTS, BRI, T1/E1 circuits) for an additional level of redundancy, beyond SIP trunk connectivity.

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 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, while the SBC 1000 and SBC 2000 provide options for physical interfaces (FXO/FWs, T1/E1, etc.) for device or PBX/ contact center migrations. The SBC SWe Edge also offers the option to be deployed in redundant pairs for high availability.

Hear the Ribbon Difference

As a security element, SBCs inherently sit in the middle of the media path between the telecom provider and phones or soft clients. Ribbon’s SBC 1000 uses that position to enhance media quality and manage interoperability between the endpoints and telecom providers. Ribbon combines dedicated DSP hardware with decades of experience building many of the world’s largest communications networks to deliver better sounding conversations. The SBC 1000 mitigates common voice quality issues our competitors often leave to chance.

The SBC 1000 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)



Managing SBC 1000

Ribbon’s SBC 1000 is managed from a centralized Ribbon Application Management Platform (RAMP) offering a complete Fault, Configuration, Accounting, Performance, and Security solution. Delivering intuitive, reliable, scalable and automated management, an enterprise can quickly configure SBCs, identify and remediate issues, deliver improved customer experience, and do so at reduced operational costs.

Ribbon Application Management Platform is designed using cloud native principles and can be deployed in multiple data center and public or private cloud environments, in standalone or high availability configurations, including options for geographic redundancy.
