## 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:\
\
\ <br>

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

<figure><img src="https://docs.telcobridges.com/w/images/a/a1/S4B_Topology_5.png" alt=""><figcaption></figcaption></figure>

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

<figure><img src="https://docs.telcobridges.com/w/images/7/73/S4B_Topology_6.png" alt=""><figcaption></figcaption></figure>

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

<figure><img src="https://docs.telcobridges.com/w/images/4/45/S4B_Topology_7.png" alt=""><figcaption></figcaption></figure>

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.\
\
\ <br>

<figure><img src="https://docs.telcobridges.com/w/images/e/ea/S4B_Topology_8.png" alt=""><figcaption></figcaption></figure>

* 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.\ <br>

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

<figure><img src="https://docs.telcobridges.com/w/images/c/c4/S4B_Topology_9.png" alt=""><figcaption></figcaption></figure>

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:<br>

<figure><img src="https://docs.telcobridges.com/w/images/d/d7/S4B_Topology_10.png" alt=""><figcaption></figcaption></figure>

## 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
```

<figure><img src="https://docs.telcobridges.com/w/images/f/fd/S4B_FreeSBC_1.png" alt=""><figcaption></figcaption></figure>

* 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\ <br>

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

* Move the selected Port range to Current section using << button.
* Click to Save button\ <br>

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
```

<figure><img src="https://docs.telcobridges.com/w/images/1/1f/S4B_FreeSBC_3.png" alt=""><figcaption></figcaption></figure>

## 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;
