Not applicable to SBC SWe Edge.

Tip

Usage of the Easy Configuration wizard to configure the SBC Edge Portfolio (SBC) does not modify existing configuration. The wizard will simply add the new configuration elements to the SBC.


The SBC Easy Configuration interface includes a built-in step-by-step wizard, which enables end-users to quickly deploy the SBC and Microsoft Teams. The SBC can be configured to connect a Microsoft Teams environment with a PSTN Provider through ISDN.

Step 1 - Configure Scenario

Note

These instructions assume the SBC Easy Configuration wizard is running. See Using the Easy Configuration Wizard.

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

  3. From the Application dropdown list, select ISDN PTSN ↔ Microsoft Teams.

    Note

    One unassigned ISDN Signaling port must be available for the ISDN application options to be displayed.


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



Scenario Field Definitions

FieldDescription
Scenario Parameters
ApplicationConfiguration template used: ISDN PSTN ↔ Microsoft Teams.
Scenario Description

Name to describe the setup.

Note

The Easy Config adds the scenario description as a prefix for all SBC configuration elements created for this deployment.

Telephone CountryCountry in which ISDN PSTN ↔ Microsoft Teams is setup.
Emergency Services

Defines the Emergency Services for outgoing numbers. For the purpose of this illustration above, Emergency Services is not selected. Related field descriptions follow.

Options:   

    • ELIN Identifier: Uses in priority order the ELIN number received by Microsoft UC.

Note

The E911 Elin number from the "CompanyName" field configured in Skype location services is used as the authoritative Call Back number for outgoing E911 calls, and is always the preferred configuration. Specifically, it will take precedence over any Callback Number number configuration in Skype Setup. For more information, see Creating and Modifying Entries to Transformation Tables.

Emergency Callback Number 1First Callback Number in string format. This field displays only when the value for the Emergency Services field is ELIN Identifier or E911/E112.
