How does Direct Routing Work, and how do I set it up? Any business online can deploy Direct Routing with relatively few problems, particularly if an organization is already using Microsoft Teams internally. Here are some steps that will help with the successful implementation of Microsoft Teams Direct Routing.
Switch your UC platform to Microsoft Teams internally If not already using Teams, organizations will benefit in terms of better communication, productivity and collaboration when considering their existing use of other Microsoft Office products.
Get the correct licenses and select your provider If you were a Skype for Business user before its retirement, and have already rolled out Teams within your organization, you'll need to ensure that your licenses include Microsoft's Audio Calls and Phone System for individual users.
Enterprises will need a third-party MSP to ensure a successful deployment of Direct Routing for Microsoft Teams. Your provider should offer system architecture design, migration, training, integration, support and more.
Session Border Controller (SBC) and SIP Direct Routing works using a Session Border Controller (SBC), which is situated at the border between networks to ensure the secure transfer of data between public and private networks. A cloud-based certified SBC will need to be configured to route calls between the MSP's network and the Microsoft phone setup.
All outgoing calls are then transmitted through to the Microsoft phone system, which then sends calls to the SBC. Through direct routing, the incoming call is sent to the Microsoft phone system and any other Teams-enabled device.
Configure media bypass In some cases, service providers implement media bypass to reduce the amount of traffic to Microsoft data centers, improving call quality. Media bypass enables you to shorten the path of media traffic and reduce the number of hops in transit for better performance. With media bypass, media is kept between the SBC and the client instead of sending it via the Microsoft Telephone System.
In non media bypass, when a client makes or receives a call, both signaling and media flow between the SBC, the Microsoft Phone System, and the Teams client, as shown in the diagram.
