HOW TO Create SIP extension on Elastix

As seen in the above topology,
Elastis is IP-PBX Server, and the IP-Phones are clients.
Our goal in this tutorial is IP-Phone Ext 101 can call Ext 102 and vice versa.
For assumptions, Elastis has IP 192.168.20.222. So we can access it from web browser https://192.168.20.222,

1. Open http://192.168.20.222 in the web browser, you will get the login page. Please fill username with 'admin' and your admin password of course.
   
2. after login you will get Elastix's 'dashboard. In this page you can see your server healthy.
   
3. For PBX configuration please click PBX tab, Now you enter PBX configuration page
   
4. Click submit for register new Generic SIP Device, input extension to be registered and the secret
• Extension :101
• Display name : Jhony
• secret : abcd1234
  
  click the submit button at the bottom
5.  repeat Step 3 and 4 for add another extension
• Extension : 102
• Display name : Mike
• secret : abcd1234
6. Now click "Apply Configuration Changes Here" for save your configuration
   
7.  Now your Elastix has two extension 101 and 102. For clients we will discuss in another article. So for the assumptions you have done register the extension on the client.
8. In this stage, extension 101 can call 102 and vice versa.
