Sbc Teams


Microsoft Teams, worldwide market leader for Unified Comunication as a Service (UCaaS) system, with the Direct Routing feature enables its customers to make external phone calls to PSTN network via a certified Session Border Controller (SBC). Italtel supports Direct Routing with its Session Border Controller (SBC) NetMatch-S.

  • Security for Deploying Microsoft Teams. Microsoft certifies Oracle Enterprise Session Border Controllers (E-SBCs) for integration with Microsoft Teams. Oracle’s E-SBC has also been certified by Microsoft to provide real-time Enhanced 911 (E911) support for Microsoft Teams Dynamic Emergency Calling for Direct Routing, protecting workers and minimizing risk during crisis situations while helping enterprises meet state and federal E911 regulations.
  • Mar 23, 2021 Microsoft Phone System Direct Routing enables you to connect your on-premises telephony infrastructure to Microsoft Teams. The article lists the high-level steps required for connecting a supported on-premises Session Border Controller (SBC) to Direct Routing, and how to configure Teams users to use Direct Routing to connect to the Public Switched Telephone Network (PSTN).

The SIP failure an SBC will provide when it cannot route a call to an upstream peer (either SIP or T1/E1 related) varies with each vendor and reason for upstream failure. If a call from Teams reaches the SBC and the SBC has nowhere to send it, you must look at the SIP Call Ladder post-call to determine what failure is being sent back to Teams.

Italtel SBC is certified by Microsoft to support Direct Routing and provides PSTN interconnection through the SIP trunking functionality, enabling Microsoft Teams to be used as a normal office phone system.

Already certified for Microsoft Lync 2013, able to support Skype for Business 2015 and to connect to Skype for Business Online via Microsoft Cloud Connector integration, NetMatch-S qualifies as reliable and effective SBC to interoperate with Microsoft UCC (Unified Communication and Collaboration) systems.
