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 Portfolio.

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.

  1. In the WebUI, click the Settings tab.

  2. In the left navigation page, access System > Node-Level Settings. The Node-Level Settings page is displayed.

  3. Configure the NTP and DNS Servers with network-specific data.

  4. Leave all other parameters as default.

  5. Click Apply.

    TLS Configuration - Example Values

    ParameterExample Value
    Host Nameaepsite6
    Domain NameRibbonMS01.com
    Use NTPYes
    NTP ServerSpecifies the FQDN, IPv4, or IPv6 address of the NTP server. If the host name is supplied, the SBC uses the DNS to connect to the NTP server.
    Use Primary DNSYes
    Primary Server IPXXX.XXX.XX.XXX

    Node-level Settings - Example

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.

Use Easy Config Wizard

Easy Config Wizard can be used to create all the resource required for Microsoft Teams Direct Routing.

Step 1: Select Microsoft Teams Connection

  1. In the WebUI, click the Tasks tab.
  2. In the left navigation panel, go to SBC Easy Setup > Easy Config Wizard.

  3. From the Application drop down list, select Microsoft Teams.

  4. Configure per the field definitions below and click Next.


    Configure Scenario Parameters - Field Definitions

    FieldDescription
    ApplicationConfiguration template used: Microsoft Teams.
    Scenario DescriptionName to describe the setup.
    Telephone CountryCountry in which Microsoft Teams is setup.
    SIP SessionsNumber of simultaneous SIP Sessions. Valid entry: 1 - 960.
    Teams ConnectionThe Teams connection type used for the network. Valid selections:
    • Teams Direct Routing
    • Teams Downstream SBC

Step 2: Configure Microsoft Teams for Endpoint

Easy Configuration Step 2 includes configuration for the Microsoft Teams endpoint. The configuration items displayed in Step 2 depends on the connection type for the Microsoft Teams leg you configured in Step 1. See below for each type. 

  1. Configure the connection type information.
  2. Click Next.


The fields below are displayed if you select Teams Direct Routing from the Teams Connection drop down list in Step 1. 


Configure Teams Direct Routing

FieldDescription

Teams Connection Type - Standalone Direction Connection

Signaling/Media Source IPClick the drop-down arrow to select the external (Internet-facing) IP address of the Microsoft Teams Direct Routing server that handles routing of messages for signaling and media.
Outbound NAT Traversal

Allows the SBC to be placed behind a NAT device, and uses the IP of the NAT device for all outgoing messages. If this field is set to Enable, the Public IP address field configuration is required. Valid selections:

Enable: Network Address Translation is used for the NAT device's Public IP address.

Disable: Network Address Translation address translation is not used.

NOTE: This field is required when the SBC interface has a private IP and the NAT device is using a public IP. For details on configuring an SBC behind the NAT, refer to Configuring the SBC Edge for NAT Traversal.

Apply ACL

Specifies whether an ACL (Access Control List) is applied to the Microsoft Teams connection. An ACL provides security to an SBC using a Public IP.

Valid selection:

True: Applies the ACL.

False: Does not apply the ACL. 

For details on configuring an ACL to be applied to an SBC, refer to Managing Access Control Lists.

ProtocolHard-coded value for protocol used with federated FQDN: TLS.
Server Port NumberHard-coded value for the port used for TLS: 5061.
Listening Port NumberPort number used for sending and receiving SIP messages between the SBC and the Border Element Server.

Step 3: Summary

Easy Configuration Step 3 includes a summary of the information configured in Step 1 and Step 3.

Review the information and click Finish.

See below for an example:
