Yes, but I had to go back after doing the dialler, and it works!
Summary:
- Create 4 numbers on the controller
- Create a Line Group “2” for “Outbound dialler” calling it “Message Playback”, save
- Give Line Group “2” 4 ports linked to the controller numbers, save
- Create a Dialler “0” called “Message Playback” with a blank access code, save
- Back into Line Group “2”, “Dialler” tab and tick the “Message Playback” dialler just created, save
- Commit then activate.
