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.
  1. In the WebUI, click the Settings tab.
  2. In the left navigation pane, go to Node Interfaces > Logical Interfaces.
  3. 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.
  4. Leave all other parameters as default.

  5. Click Apply.

Create Profiles

For interconnecting with Microsoft System Direct Routing, the following profiles are required:

  • Teams Direct Routing Profile (SIP)
  • Analog Device Profile

Create Teams Direct Routing Profile

The Teams Direct Routing profile is used for connecting the SBC Edge to Microsoft Teams.

Create the Teams Direct Routing Profile as follows:

  1. In the WebUI, click the Settings tab.
  2. In the left navigation page, access SIP > SIP Profiles.
  3. Click the ( ) icon at the top of left corner and add a new SIP profile.
  4. 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.
  5. Leave all other parameters as default.

  6. Click OK.

    SIP Profile Configuration - Example Values

    ParameterExample Value
    DescriptionTeams Direct Routing Profile
    FQDN in From HeaderSBC Edge FQDN
    FQDN In Contact HeaderSBC FQDNNOTE: For Microsoft Teams, the Signaling Group facing the Teams server must be configured as SBC Edge FQDN or Static (if there is more than one signaling group connected to Teams Direct Routing). The FQDN in Contact Header should be the same FQDN used in Office 365 Tenant Online Gateway. If the IP Address of the SBC is configured in the Contact Header instead of the FQDN of the SBC, a Forbidden message is received.NOTE: If you set this field to Static and you expect the port number of the Contact header in the outbound SIP messages, you must configure the Static Host FQDN/IP field with the Listen Port number of the SIP signaling group.
    Origin Field Username <FQDN of SBC> (in the example aepsite6.SonusMS01.com)

    SIP Profile - Example

Create Analog Device Profile
