You probably did not configure connection to your Asterisk server properly, or you didn’t check Asterisk config View within Visual Dialplan where the configuration data is presented. Check it both – open Preferences window and test connection to your Asterisk server, and then open Asterisk config view to see the configuration.

After you configure the connection to your Asterisk server (Preferences dialog) make sure to click on the ‘Detect’ button to instruct Visual Dialplan to connect to Asterisk server and read configuration data. If successful, the confirmation message with info about Asterisk server will be presented.
