The Ribbon Session Border Controller 2000 (SBC 2000) is an ideal security and interoperability solution for medium-sized businesses and large branch offices. The SBC 2000 delivers:

  • VoIP Security (topology hiding, encryption, protection against Denial of Service attacks, and more)
  • Interoperability with leading PBXs, cloud UC services, 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 and PRI
  • Advanced call routing features such as Active Directory/LDAP server routing integration and onboard call forking
  • Centralized management from the Ribbon Application Management Platform (RAMP)


The SBC 2000 is the right choice for any organization or site with up to 1000 employees. The SBC 2000 protects SIP trunks and cloud UC services, including Microsoft Teams. Its scalability and support for up to 16 T1/E1 spans make it an ideal solution to support existing call centers or to retain a legacy PBX as part of a long-term migration strategy. Organizations that need to connect traditional analog phones (such as cordless phones, elevator phones, door phones, fax machines, etc.) will appreciate the SBC 2000’s FXS ports. Like every Ribbon SBC, the SBC 2000 has been independently verified to deliver full protection and performance, even during severe security attacks. That performance helps assure those bad actors won’t disrupt your communications when you need them most.

The SBC 2000’s intuitive web interface, including multiple ready-to-use configuration parameters, makes it easy for organizations to upgrade to the latest unified communications services, even when they may be retaining an on-site contact center or migrating from a legacy PBX. License-based sessions and port expansion eliminate the need for a truck roll and/or an on-site technician.

The Ribbon SBC 2000 is certified for Direct Routing with Microsoft Teams, Zoom Phone BYOC, Webex Local Gateway, Google SIP Link, and has been deployed with nearly every popular cloud service and telecom provider. 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 2000 (Server Module required). The SBC 2000 already provides support for resilient WAN connections, and 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 2000’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 2000 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.

Software and Cloud Options

Easily deploy Ribbon SBC software in multiple virtual environments

The SBC 2000 is an ideal solution for customers that want or need a scalable on-site, hardware-based solution. In addition, Ribbon offers the SBC 2000’s robust security capabilities as software from the cloud. Ribbon’s Session Border Controller, Cloud Native Edge (SBC CNE Edge), and Software Edition Edge (SBC SWe Edge) are software options that operate in virtual machines or the public cloud (Azure or AWS). In minutes, an organization can deploy a Ribbon SBC to enable Teams Direct Routing, Zoom Phone BYOC, or to connect almost any other cloud UC service to a telecom provider. Organizations get the same ease of use and robust security services without having to deploy hardware. And, since it’s in the cloud, it can scale up or down as needed. Ribbon even offers a 30-day trial license so your organization can test it out.
