Dialog State Notifications

From Pbxnsip Wiki

In order to receive the dialog state notifications from the PBX, you will have to follow these steps

1. Login to the PBX.
2. Select any registered user/extension account for editing.
3. Select the 'Registration' tab
4. At the bottom on the page, you will see "Add Contact" section
5. Type in 'http://your-crm-server-address/your-server-handler-file' (something like http://192.168.1.10/pbxhander.php)
6. Click "save"
7. Observe that a 'dialog' entry is added to the list of registration (just above the 'Add Contact')

This will setup the PBX to send dialog state notifications to the 'your-crm-server-address' whenever call activity happens on the user/extension.

A sample output from the PBX is shown below
