Sonus Cloud Link for Microsoft CCE


Sonus Cloud Link is an integrated appliance solution that combines Sonus’ award winning SBC 1000 and SBC 2000 session border controllers running embedded Microsoft Skype for Business Cloud Connector Edition software. Sonus Cloud Link provides a complete solution to enable enterprises to transition from traditional voice deployments to a Microsoft Skype for Business implementation whether on-premises or in the cloud with Microsoft Office 365 Cloud PBX.

Microsoft Skype for Business Cloud Connector Edition

Microsoft Skype for Business Cloud Connector Edition is software that is used to connect an enterprise’s telephony environment with Office 365 Cloud PBX. Cloud Connector Edition provides local access to the PSTN as an alternative to Microsoft’s PSTN access in the cloud, which is necessary for the following reasons:

  • Microsoft may not offer cloud PSTN access in some regions/jurisdictions
  • Enterprises often have existing contracts with Service Providers that may be difficult or costly to terminate early
  • Enterprises may choose to remain with their current Service Provider regardless of the availability of the Microsoft cloud-based PSTN access

Sonus Cloud Link

Sonus Cloud Link integrates Skype for Business Cloud Connector Edition in a single, flexible and secure appliance that reduces CAPEX associated with server hardware and software procurement and implementation. Sonus Cloud Link also preserves existing PSTN connectivity, supports legacy PBXs and analog devices, and provides an enterprise-wide legacy dial plan and Active Directory dial plan integration to help customers migrate to Office 365 Cloud PBX at their own pace with no disruptive cutover. Powered by Sonus’ SBC 1000 and SBC 2000 session border controllers, Sonus Cloud Link delivers robust security features to prevent unauthorized access and preserve communications through hacker attacks.


Simple to install, easy to configure

Sonus Cloud Link comes pre-loaded with Microsoft Cloud Connector Edition software and all necessary licenses required to install the solution, saving time and cost associated with sourcing servers and software separately. Additionally, the included Cloud Connector Edition GUI Setup Wizard significantly reduces the complexity and time needed to configure Cloud Connector Edition, enabling fast and efficient deployments.
