Skype for Business Hybrid Deployment:

Office 365 – Cloud PBX with on-premises PSTN Connectivity

As a Microsoft Gold Communications Partner, Sonus delivers the expertise required by enterprises to enable a secure, reliable and seamless migration to a Skype for Business hybrid deployment.

Sonus Session Border Controllers (SBCs), which are certified with Skype for Business, are commonly deployed by customers at the border between the enterprise’s on-premises Skype for Business deployment and the service provider’s network, providing an effective demarcation point for media transcoding, network security, robust Session Initiation Protocol (SIP) interworking, intelligent call routing and multi-vendor interoperability.
