Configuring Skype for Business Server 2015

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

Adding ProSBC 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:

S4B Topology 1.png

2. Run Topology Builder. The Following is displayed,

S4B Topology 2.png

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:

S4B Topology 4.png

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

S4B Topology 5.png

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

S4B Topology 6.png

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 ProSBC 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 ProSBC. This parameter is later configured in the S4B NAP settings.
  • Click Finish.

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

9. Publish the Topology; In the main tree, select the root node Skype for Business Server, and then from the Action menu, choose Publish Topology, as shown below:

S4B Topology 10.png

In the new window click Next; the Topology Builder starts to publish your topology, as shown below:

S4B Topology 11.png

10. Wait until the publishing topology process completes successfully, and click Finish as shown below:

Configuring ProSBC for Skype for Business Server 2015

This procedure describes how to configure Skype For Business in ProSBC to route calls to external ITSP.

1. On the ProSBC, need to add a new SIP Transport Server for TCP Connection

  Go to SIP -> Click to Configured SIP -> Transport Servers -> Create New Transport Server



S4B FreeSBC 1.png

  • Give a Name for this transport server
  • Set Port Type to TCP
  • Set the listening transport server Port. It must be the same as configured on Skype For Business IP/PSTN Gateway (In this documentation section 7)
  • Set the IP Interface for transport server listening on.
  • Click to Save button

2. Add a NAP for Skype for Business Server Go to NAPs -> Create New NAP

S4B FreeSBC 2.png

  • Give a Name for this NAP
  • Click to Create button



S4B FreeSBC 2 1.png

  • Select SIP Transport Server for this NAP. It must be the same SIP Transport Server we created for Skype for Business before (Section 1)
  • Move the selected SIP Transport Server to Current section using << button



S4B FreeSBC 2 2.png

  • Set Skype for Business Mediation Server FQDN address in the Proxy Address Check the following link for DNS configuration v3.1: DNS configuration
  • Set Skype for Business Mediation Server Port in the Proxy Port



S4B FreeSBC 2 3.png

  • Select the correct Port range for this NAP
  • Move the selected Port range to Current section using << button.
  • Click to Save button

3. Add routes for Skype for Business Server

You need to add 2 routes for Skype for Business Server. One for Incoming traffic from Skype for Business Server and other for outgoing traffic to Skype for Business Server.

1. For Incoming traffic from Skype for Business Server

        Go to Routes -> Create New Static Route



S4B FreeSBC 3.png

  • Give a Name for this route
  • Select incoming NAP. Select the NAP we created before for Skype for Business
  • Select outgoing NAP from Remapped NAP
  • Click to Create button

2. For Incoming traffic to Skype for Business Server

        Go to Routes -> Create New Static Route 



S4B FreeSBC 3 1.png

  • Give a Name for this route
  • Select incoming NAP.
  • Select outgoing NAP from Remapped NAP. Select the NAP we created before for Skype for Business

Activating the Configuration

Changes made to the configuration of the ProSBC units are stored in the OAM&P Configuration and Logging database. In order for changes to be used by the system, they must first be activated. This is done at the system level and accessed from the Navigation panel.

Check the following link for activating the configuration;
