Tutorial - Create Simple VoIP-network with Billion Softswitch Step by step we will build the system consisting of following components, see picture below: VoIP proxy-server presented by the computer with established on it BSS – ip-address: 10.0.0.1, Two IP-phones, presented by computers with X-lite softphones installed (http://www.counterpath.net/X-Lite-Download.html) – ip-addresses: 10.0.0.2 and 10.0.0.3, IP-telephony gateway (in our example, D-Link DVG 6004S) with four FXO-ports, providing integration with a public telephone line – ip-address: 10.0.0.4. The system will have also connection with a SIP-network, for making long-distance and international calls. This scenario assumes that you have already successfully installed and started BSS on your computer (hereafter, PC1).

Step 1. Registration of IP-phones on Billion Softswitch

IP-phones (in our example – softphones installed on personal computers) can be registered on BSS as subscribers. This is because Billion Softswitch could check their status (on- or off-line). To register ip-phones on BSS click "Subscribers" item in the main menu of configuration page and do the following:

• For PC 2:
• Description: PC 2
• Account: 101
• «Additional parameters»: Login: 101, Password: 101 (or any another at will). Press button "Accept" in a popup window of additional parametres.
• In the "Action" column choose in the drop-down menu "Add"
• Press "Accept" button under the subscribers table
• for PC 3:
  • Description: PC 3
  • Account: 102
  • «Additional parameters»: Login: 102, Password: 102 (or any another at will). Press button "Accept" in a popup window of additional parametres.
  • In the “Action" column to choose in the drop-down menu «Add bottom»
  • Press "Accept" button under the subscribers table.

In X-Lite drop-down menu open dialog “SIP account settings” and enter the following properties of the account:

• Display name: 101 or 102
• User name: 101 or 102
• Password: 101 or 102 (or what has been entered in Billion Softswitch)
• Domain: 10.0.0.1
• Check “Register with domain and receive incoming calls”.

After setting up completion ip-phones will try to register on BSS. The registration status of ip-phones can be checked on the page «Subscribers status» in configuration panel of Billion Softswitch. If in the table on this page we see two lines corresponding to our ip-phones, then, this step is successfully finished.

Step 2. The call from one ip-phone to another through Billion Softswitch

Now a test call from one ip-phone to another can be made.

In a window of ip-phone PC 2 enter the number of ip-phone PC 3: 102 and press the call button. The call should be established. You can check the call status on the page «Calls status» in Billion Softswitch configuration panel.

Step 3. Call to a public phone line (PSTN)

Now, having connected two ip-phones, we have created the elementary internal VoIP-network.

To have possibility to make calls to public numbers, it is necessary to include into our system a gateway providing integration of a VoIP-network with PSTN. In our example it will be D-Link DVG-7022S. As shown on the scheme, the gateway’s ip-address is 10.0.0.4. In Billion Softswitch configuration panel on Terminators page add the following record:

• Description: D-Link gateway
• Protocol: SIP
• IP-address or a name: 10.0.0.4

We have added the terminator to the system. Now we need to create a route for calls to this terminator. In order to get to public line let’s agree to type 9 before the phone number.

Open page "Routes" in Billion Softswitch configuration panel. Let’s add a new line:

• Description: PSTN calls
• Prefix: 9~
• Rule of change of number: ~
• In Additional parameters window choose the only terminator «D-Link gateway; sip:10.0.0.4».

The prefix «9~» means «all calls, which dialed number begins with 9». As we have left Number translation rule by default equal to «~», then beginning 9 in dialed number will be removed from the call sent to terminator.

Now we can make a test call to public phone number. In the ip-phone window on PC 2 enter phone number started with prefix 9 and press the call button. The call should be established. You can check call status on the page «Calls status» in Billion Softswitch configuration panel.

Step 4. Connection to SIP-network

In order to be able to make long-distance calls under lower price, we can connect our system to an Internet telephony network (SIP-network). As well as in the Step 3, we need to create a terminator and a route. Let’s open page "Terminators" and we add new record:

• Description: SIP network
• Protocol: SIP
• IP-address or domain name: sip-network-domain
• In additional parameters enter Login and Password received by you at registration in a SIP-network.

Let’s agree that for long distance calls the subscriber will dial prefix 0 before phone number. Now we will open page "Routes" and add new record:

• Description: Long distance
• Prefix: 0~
• Rule of change of number: ~
• In a window of Additional parameters to choose терминатора "SIP network; sip:1.1.1.1"

Now we can make a test call to long-distance number. In the ip-phone window on PC 2 enter phone number with a prefix 0 in a format and press the call button. The call should be established. You can check call status on the page «Calls status» in Billion Softswitch configuration panel.

Summary

So, we have built the elementary network of the VoIP-telephony, allowing to make internal vocal calls, and also to call on PSTN and long-distance numbers. You can expand functionality of your network, using the various Billion Softswitch functions. If you have any questions, wishes or ideas how to make Billion Softswitch even more useful tool, we will be glad to hear from you.
