 ## 9.) Create Extensions
+An “extension” is the name for any destination on the Asterisk phone network – it defines the number that is dialled to call a physical telephone, a “virtual” software telephone, or access a “feature” service (like the speaking clock or an automated message line). Every number that you want players to be able to dial a number and have something happen needs to have an associated extension.
+To create a new extension associated with a telephone, perform the following steps:
 - a.) Go Connectivity->Extensions
 - b.) Add Extension + Add New SIP [chan_pjsip] Extension
 - c.) There are several options, but only three are required:

+# Connecting a Phone Handset to an Extension
+To connect a regular analog phone to the network requires a VoIP phone adaptor. This section explains how to configure the Linksys PAP2T device to map the handset plugged into Line 1 to the extension created in the previous section. Note that if you use a different ATA your settings may differ slightly, but the general approach should remain the same.
+- a.) Open a web browser and navigate to the web interface for your ATA device.
+- b.) Log on to the management screen (click the Admin Login link at the top right of the page), and click on the Line 1 tab to configure the device plugged into Line 1.
+- c.) Change the following settings:
+  - **Proxy**: This should be set to the static IP address assigned to your Raspberry Pi running Asterisk. E.g. 192.168.1.33.
+  - **Display Name**: This should match the “_Display Name_” set in the FreePBX extension configuration in the previous section.
+  - **User ID**: This should match the “_User Extension_” set in the FreePBX extension
+  - **Password**: This should match the “_Secret_” set in the FreePBX extension
+

+
+# Creating a Virtual Softphone
+You can also make and receive calls using a software client mapped to an extension. I’m using the free program MicroSIP to simulate a VOIP phone on my PC.
+- a.) Download MicroSIP from https://www.microsip.org/
+- b.) Set up account information as follows:
+  - **Account Name**: This should match the “_Display Name_” set in the FreePBX extension
+  - **SIP Server** and **SIP Proxy**: These should both be set to the static IP address assigned to your Raspberry Pi running Asterisk. E.g. 192.168.1.33.
+  - **Username**: This should match the “_User Extension_” set in the FreePBX extension
+  - **Domain**: This should be set to `localhost`
+  - **Password**: This should match the “_Secret_” set in the FreePBX extension
+-
+- Setup the connection information as shown in Figure 8. 
+As when setting up the ATA in the previous section, the Username and Password must match the Extension and Secret set up in Asterisk
+The SIP Server and SIP Proxy should be the IP address assigned to the Raspberry Pi that is running Asterisk.
+Domain should be set to “localhost”
