Hi there,

I and my customers have noticed that there are no ring-back tones when we make calls. If I call my numbers externally, there is nothing to hear on the line, neither busy, nor a ring-back tone.

Does anyone have any idea why?

  Problem solved. For incomprehensible reasons, inbound progress was enabled on the trunks. After I disabled this, everything runs again.
