Enhanced Gateways

SIPHON offers a comprehensive range of platforms to enable the integration of On-Premise, Hybrid or Cloud based Skype for Business environments with TDM PBXs / IP-PBXs, and PSTN / SIP Trunking providers. The portfolio includes:

  • Enhanced Gateways
  • Appliances with Integrated Skype for Business Cloud Connector Edition (CCE)
  • Survivable Branch Appliances


Enhanced Gateways enable controlled migrations towards Microsoft UC providing advanced routing features & add-on software solutions (e.g. Emergency calling and E911). Our gateway portfolio support both TDM and IP-based PBX integration, PSTN connectivity, as well as integration with a variety of fixed and mobile end-points.


CCE Appliance bundles incorporate proven Session Border Controllers (SBC) and Gateways with the Skype for Business Cloud Connector Edition, into an elegantly packaged platform that is easy to deploy and manage. This enables integration of Office 365 Enterprise Voice with on premise PBXs and / or PSTN connectivity.


Survivable Branch Appliances (SBAs) are an essential element for multisite deployments of Microsoft Unified Communications. SBAs provided by SIPHON are fully certified by Microsoft and ensure continued access to Microsoft UC services, including voice and data communications, during WAN outages.
