The PSX SWe is the virtual, cloud-native version of our centralized policy and routing solution, providing intelligent session control for enterprise-wide VoIP services. Fitting seamlessly into an enterprise’s virtual and cloud strategy, PSX SWe can be deployed in a private data center or cloud or on an enterprise’s virtual portion a public cloud.

With PSX SWe, an enterprise can:

  • Intelligently manage routing paths as well as establish call prioritization and configure call admission control
  • Bring together multi-vendor PBX environments to create centralized dial plans across disparate platforms
  • Reduce costs through centralized operational efficiencies, simplified network management and a single point of provisioning reducing the potential for provisioning errors
  • Avoid or reduce international and long-distance toll fees by keeping traffic within the enterprise and leveraging least cost routing for off-network traffic
  • Manage PBX migration to cloud-based solutions through integration with Microsoft Active Directory

Simplify Service Migration To the Cloud

PSX SWe provides centralized routing and policy engine in a multi-vendor enterprise environment, significantly simplifying migration from an on-premises PBX to a cloud-hosted unified communications or call center service.

By caching user profile information (for example from Microsoft Active Directory) the PSX SWe can very efficiently use that information to make routing decisions without having to access MSFT AD for every call.

With PSX SWe it will no longer be necessary to do duplicate provisioning and routing for legacy and cloud-based solutions.

For each incoming call, the PSX will be able to:

  • Determine if the called party is still on a legacy endpoint or a cloud endpoint
  • Route call to the cloud if the called party line is already migrated or to the legacy endpoint if not migrated
  • If desired, fork the call to both legacy PBX and MS Teams based on user profile attributes
  • Forwarding calls to other user-owned numbers based on policy

Ribbon Quality of Service Routing

Quality of Service Routing Diagram

QoS based routing provides the most advanced intelligent routing based on combining the least cost with quality of service (QoS) metrics of that Trunk Group. This type of routing allows enterprises to reduce costs and increase the quality of service for their customers and employees by selecting the most appropriate TGs based on a variety of criteria, including LCR rates, service level agreements (SLAs), voice quality, and network capacity. Because of the complexity of LCR calculations and the number of variables involved, only a centralized policy and routing server can efficiently aggregate all the information and calculate the optimal routes and do so with minimal post-dial delay.

Intelligent Session Control for Enterprise


Ribbon Application Management Platform

Ribbon’s PSX SWe is managed from a centralized Ribbon Application Management Platform (RAMP) solution, offering a complete set of Fault, Configuration, Accounting, Performance, and Security features.

By delivering intuitive, reliable, scalable, and automated management, it is possible to quickly define policy and routing configurations, identify and remediate issues, deliver improved customer experience, and do so at reduced operational costs.

Ribbon Application Management Platform manages both primary and secondary (replica) PSX SWe deployed across private data centers and private or public cloud environments The platform itself is designed using cloud-native principles and can be deployed in multiple data centers and public or private cloud environments in standalone or high availability configurations, including options for geographic redundancy.
