Cloud-Hosted SBC for Microsoft Teams Direct Number Routing

SBC (Session Border Controller) is a device or software component that undertakes security and signal processing tasks in communication networks. It is necessary for Teams Direct Routing because it allows Teams users to access external lines and make calls via PSTN (Public Switched Telephone Network). It also manages functions such as security, translation, instant messaging, and media management.

Teams Direct Routing enables PSTN connections via Microsoft Teams. This allows Teams users to connect to regular phone lines. SBC is used to provide signal conversion and security between Teams servers and PSTN operators.

Microsoft has certified certain SBCs for Teams Direct Routing. Among these certified SBCs are products from companies such as TeamsHere, IQsbc, and Cloud360. Using these certified SBCs provides advantages in terms of compatibility and performance.

Microsoft subjects SBCs to certain tests for certification and verifies their compatibility for Teams Direct Routing. These certified SBCs offer seamless integration and support with Teams. They are also continuously supported for Microsoft updates and changes.

SBC configuration typically includes network and security settings such as SIP (Session Initiation Protocol) trunks, firewall rules, NAT (Network Address Translation) configurations, and communication protocols. These settings are critical to ensure secure communication and seamless integration with Teams.

Teams and SBC integration usually follows the steps documented by Microsoft. These steps include correctly configuring the SBC with Teams, updating the SBC, and making the necessary network settings to enable communication with Teams.

Using SBC can improve voice quality and ensure security in Teams. SBC optimizes voice traffic, provides QoS (Quality of Service), manages firewall transitions, and encrypts voice traffic. This offers a more secure and high-quality communication experience.

The correct positioning of SBC usually depends on the company's network and usage scenario. Best practices include redundancy for high availability, using security and performance monitoring tools. Additionally, a regularly updated and managed SBC is important.

Cloud-based SBCs generally offer a more flexible, scalable, and easier-to-manage option. On-premises SBCs typically provide more control and customization but may have higher installation and maintenance costs.

SBC management usually involves using management tools and reporting dashboards provided by the SBC manufacturer. Additionally, Microsoft's management tools and support resources for Teams can also be utilized.
