Configuring Skype for Business Server 2015

This procedure describes how to configure FreeSBC as an IP /PSTN Gateway in Skype for Business.

Adding FreeSBC in to S4B Topology

1. On the server where Topology Builder is installed, start the Skype for Business Server 2015 Topology Builder (Windows Start menu > search for Skype for Business Server Topology Builder), as shown below:

2. Run Topology Builder. The Following is displayed,

3. Select the Download Topology from existing deployment option, and then click OK; you are prompted to save the downloaded topology. Enter a name for the topology file and then click Save.

The Topology Builder screen with the downloaded topology is displayed:

4. Under the Shared Components node, right-click to PSTN gateways node, and then from the menu, choose New IP/PSTN Gateway

5. Enter the Fully Qualified Domain Name (FQDN) of the FreeSBC (e.g., freesbc.telcoway.local). Click Next

6. Define the listening mode of the Ip address of your new PSTN Gateway, click Next.

7. Define a root trunk for the PSTN gateway. A trunk is a logical connection between the Mediation Server and a gateway uniquely identified by the following combination: Mediation Server FQDN, Mediation Server listening port (TLS or TCP), gateway IP and FQDN, and gateway listening port.

• In the 'Listening Port for IP/PSTN Gateway' field, enter the listening port that the FreeSBC will use for SIP messages from the Mediation Server that will be associated with the root trunk of the PSTN gateway (e.g., 5060). This parameter is later configured in the SIP Transport Server.
• In the 'SIP Transport Protocol' field, select the transport type (TCP) that the trunk uses. This parameter is later configured in the SIP Transport Server.
• In the 'Associated Mediation Server' field, select the Mediation Server pool to associate with the root trunk of this PSTN gateway.
• In the 'Associated Mediation Server Port' field, enter the listening port that the Mediation Server will use for SIP messages from the FreeSBC. This parameter is later configured in the S4B NAP settings.
• Click Finish.
  
  

8. The FreeSBC added as a PSTN Gateway, and a trunk is created as shown below:
