Run the Easy Configuration Wizard to deploy a Microsoft Teams Direct Routing scenario. Refer to the following configurations under Working with SBC Easy Configuration:
IP Routing must be customized in the SBC SWe Lite for Microsoft Teams Direct Routing in Azure. Two options are available for configuration:
...
When using multiple NICs on the SBC SWe Lite, Azure designates the first Network's Interface as the Primary Network Interface. Only the Primary Network Interface receives a network default gateway and routes via DHCP. To assign the Network Default Route on another Subnet, you must designate another Network's Interface as the Primary Network Interface.
To assign the network default route, refer to Change Azure Default Route.
...
Add a static route for the traffic to the following IP address and Mask: 52.112.0.0/14 (52.112.0.0/255.252.0.0).

For details on creating Static Routes, refer to Creating Entries in a Static IP Route Table. |
Add the following Static Route using your media interface:
Destination IP: 52.112.0.0

Before configuring Outbound NAT Traversal, obtain the Public IP address for your network (the Public IP address specified in the screen graphic is an example only). |
Configure the Outbound Static NAT for all Signaling Groups that use an interface with a Public IP address (at the minimum for the Microsoft Teams Direct Routing Signaling Groups).
From the NAT Public IP (Signaling/Media) drop down list, enter the Public IP Address assigned on this media port (the Public IP used in the screen is an example only; use the Public IP for your network).

Hosting SBC in Microsoft Azure reduces the need for Direct Routing Media Bypass (Media Bypass in Azure is not recommended but will be supported in a future release). As a result, ICE Lite and RTCP Multiplexing must be disabled on the Teams Direct Routing Signaling Group, as follows:
Select the Signaling Group used for Microsoft Teams Direct Routing.
From the RTCP Multiplexing drop-down list, select Disable.
