SBC Software Edition (SBC SWe)

Ribbon's SBC Software Edition (SWe) is identical software to its award-winning SBC 5000 series and SBC 7000 product – just without the appliance.

Ribbon's virtualization strategy capitalizes on its heritage of enabling secure, reliable and scaleable real-time communications.  With the cloud native SBC SWe, service providers can be sure they will be able to deliver secure real-time communications on almost any private or public cloud environment without compromising scale and performance – and without needing a truck roll.

Use the SBC SWe to meet or exceed the demanding requirements you have for SIP trunking, Network-Network Interconnect, Unified Communications as a Service, or Contact Center as a Service.  Use the SBC SWe to simplify migrate from TDM to IP peering and offer the SBC as a Service to enterprise customers.

The SBC SWe provides robust interworking for multiple signaling protocols, call admission control to manage traffic levels, multiple security features to protect privacy and ensure regulatory compliance, media (RTP) packet processing, and audio transcoding.

SBC SWe as a Virtual Network Function (VNF)

Many service providers are implementing and expanding their deployment of network functions virtualization (NFV) in their private cloud. NFV is intended to eliminate proprietary hardware dependencies, drive efficiency of scale, improve service agility and fundamentally improve the way service providers do business. By delivering the SBC SWe as an OpenStack-based VNF, Ribbon helps ensure successful cloud deployments for real-time communications.

As an alternative, service providers can deliver real-time communication services from a public cloud. And much like a private cloud implementation, to do so, requires an SBC to ensure security, performance, and availability. Public cloud-hosted applications, such as: unified communications; conferencing and collaboration; and contact centers, benefit from being able to deploy Ribbon’s cloud-native SBC SWe on Amazon Web Services (AWS), Google Cloud Platform (GCP) or Microsoft Azure.


Benefits of deploying SBC SWe on a public cloud:

  • Achieve much faster time-to-market than having to procure, install, and implement the required compute, networking and storage infrastructure on a private cloud or a data center
  • Reduce operating costs by eliminating the need for ongoing maintenance of the cloud infrastructure because the public cloud provider handles this now
  • Gain flexibility and cost control when scaling SBC capacity, because public cloud resources are available on a subscription basis.

Bandwidth Deploys Ribbon SBC SWe on AWS Case Study

Ribbon’s SBC SWe is a powerful cloud-native solution that can scale up or down via simple software licenses, allowing operational teams to dynamically adjust scale in minutes, rather than in hours, days or months

AWS Marketplace

The SBC SWe is available through the AWS Marketplace using a Bring Your Own License or Pay-As-You-Go model making it simple to access, instantiate and deploy on AWS. Pay-As-You_Go licensing is available through qualified Ribbon resellers. Potential customers looking for a preset configuration of the SBC SWe and a FreePBX server for basic testing can find the SBC SWe as an AWS Quick Start.

For more details on an AWS deployment read our blog post “Deploying a Session Border Controller in Amazon Web Services.”

The SBC SWe Pay-As-You-Go license model is intended for customers who need to deploy an SBC for Amazon Chime Voice Connector, the AWS’ SIP trunking service that offers a secure, global calling service with pay-as-you-go pricing and no upfront fees. The SBC SWe provides Amazon Chime customers security, high availability and interoperability for Voice over IP (VoIP) traffic being sent to and from Amazon Chime Voice Connector. This includes support for Direct Routing for Microsoft Teams.

For more details on our support for Amazon Chime Voice Connector, download our solution brief “Ribbon SBC SWe Supports AWS Chime Voice Connector” or read our press release “Ribbon’s Session Border Controller Adds Support for Amazon Chime Voice Connector”

Session Border Control as a Service (SBCaaS)

By harnessing the power of network functions virtualization (NFV) it is now possible to offer Session Border Control as a Service (SBCaaS). As a managed service, Ribbon's SBC SWe can be deployed at the edge of a service provider's cloud in a virtual Customer Premise Equipment (vCPE) model, on the enterprise customer premises, deployed in a universal Customer Premises Equipment (uCPE) model, or on a public cloud.

Benefits for the Service Provider

  • Turn up services for customers in minutes/days rather than weeks/months
  • Optimize total cost of ownership using orchestration, virtual machine resources and commercial off the shelf (COTS) platforms
  • Elasticity to match virtual resources to dynamic traffic profiles

Benefits for the Enterprise

  • Eliminates need to procure, install, deploy, and maintain SBCs
  • More easily align required SBC capacity with seasonal business or high variability in traffic levels
  • Provides the ability to add/reduce capacity using a pay-as-you-go subscription model


The SBC SWe plays an important role as an enabler for our customer’s implementation of STIR/SHAKEN.

The SBC SWe supports the following capabilities:

  • Relay STIR/SHAKEN information in SIP headers
  • Generation of an authentication or verification requests to the PSX and update of the information in the SIP message per the response from the PSX.
  • Flexible handling of error conditions if signature verification fails
  • Ability to receive updated STIR/SHAKEN information based on SIP Redirect query

In addition, SBC SWe CDRs can be fed into Ribbon Analytics to assist in determining potential robocall or fraud call attempts as part of the Ribbon's Identity Assurance solution
