These instructions assume the SBC Edge is installed and running, and is connected to the WebUI.
For the purposes of this documentation, the screens displayed are for an SBC 1000/2000; the interface configuration may vary slightly for the SBC SWe Edge. If configuration is not specified for a field, use the default value.
Access the SBC Edge WebUI
Access the WebUI. Refer to Logging into the SBC Edge.
Configure TLS Profile
The TLS profile defines the crypto parameters for the SIP protocol; it is used as the transport type for incoming and outgoing SIP trunks.
Configure a TLS profile as follows:
- In the WebUI, click the Settings tab.
In the left navigation pane, go to Security > TLS Profiles.
- Click the Create TLS Profile ( ) icon at the top of the TLS Profile page. The Create TLS Profile page is displayed.
Configure the parameters as shown below (example values are shown in the table; configure as per your network requirements). For details on field descriptions, refer to Creating and Modifying TLS Profiles.
Leave all other parameters as default.
Click OK.
Configure Host Information and DNS
The Host Information and DNS configuration contains system information that is used by the SBC Edge, including host, domain, and NTP server information.
- In the WebUI, click the Settings tab.
In the left navigation page, access System > Node-Level Settings. The Node-Level Settings page is displayed.
Configure the NTP and DNS Servers with network-specific data.
Leave all other parameters as default.
Click Apply.
Configure Logical Interface
The SBC Edge supports system-supported Logical Interfaces, which are used to hold the IP address for each Ethernet port. One of these logical interfaces is assigned an IP address for transporting the VoIP media packets (i.e., RTP, SRTP) and protocol packets (i.e, SIP, RTCP, TLS). In this example, Ethernet 1 is configured for transporting packets for the Microsoft Teams Direct Routing connection.
Ensure the IP Routing Table contains the same information as in the network topology.
- In the WebUI, click the Settings tab.
In the left navigation pane, go to Node Interfaces > Logical Interfaces.
Configure the parameters as shown below (example values are shown in the table; configure as per your network requirements). For details on field descriptions, refer to Configuring and Modifying Logical Interfaces.
- Leave all other parameters as default.
Click Apply.
Create SIP Profile
The SIP Profile controls how the SBC Edge communicates with SIP devices; the profile controls important characteristics such as: session timers, SIP header customization (including FQDN), SIP timers, MIME payloads, and option tags .A SIP Profile also defines which FQDN (Fully Qualified Domain Name) is used in the Contact Header and From Headers. For interconnecting with Microsoft System Direct Routing, two SIP Profiles are required:
- Teams Direct Routing Profile
- SIP Trunk Profile
Create Teams Direct Routing Profile
Create a SIP Profile for the Teams Direct Routing Profile as follows:
- In the WebUI, click the Settings tab.
- In the left navigation page, access SIP > SIP Profiles.
Click the (
) icon at the top of left corner and add a new SIP profile.Configure the parameters as shown below (example values are shown in the table; configure as per your network requirements). For details on field descriptions, refer to Creating and Modifying SIP Profiles.
Leave all other parameters as default.
Click OK.
Create SIP Trunk Profile
Create a SIP Profile for the SBC Edge's SIP Trunk as follows:

- In the WebUI, click the Settings tab.
- In the left navigation page, access Media > Media List.
- Click the ( ) icon at the top left corner and add a new Media List.
Configure parameters as shown below. For details on field descriptions, refer to Creating and Modifying Media Lists.
Leave all other parameters as default.
Configure a SIP Server Table
SIP server tables define the information for the SIP interfaces connected to the SBC Edge; a SIP Server Table is required to support the Microsoft Phone System. For interconnecting with Microsoft System Direct Routing, two SIP Profiles are required:
- Teams Direct Routing Server
- SIP Trunk Server
Create a Teams Direct Routing Server
- In the WebUI, click the Settings tab.
- In the left navigation page, access SIP > SIP Server Tables
Click the (
) icon at the top left corner and add a new SIP Server Table.- For Description, enter Teams Direct Routing Server.

Configure Entries in the Teams Direct Routing Server
The information you configure in the SIP Server table pairs the SBC Edge to the Microsoft Teams Direct Routing interface. Three entries in the SIP Server table offer server redundancy to ensure a server is always up and communicating. If a server is down or not communicating, the SBC Edge will automatically move to the next Server entry on the list.
Configure Teams Direct Routing Server entries as follows:
- In the WebUI, click the Settings tab.
- In the left navigation page, access SIP > SIP Server Tables.
- Select the name of the table created in the previous step.
- From the Create SIP Server drop down list, select IP/FQDN.
Repeat this configuration for two additional SIP Server entries, using the field entries below. For details on field descriptions, refer to Creating and Modifying Entries in SIP Server Tables.
Create a SIP Trunk Server
- In the WebUI, click the Settings tab.
- In the left navigation page, access SIP > SIP Server Tables
