Well, my be the description is not the best: what happens is, when i get an inbound call, the call is sent to a ring group, if not answered, it’s sent again to a different group. The caller listens to music of MOH, but a small silence or a “click” is heard in this group changing. It’s not very elegant. The “jumping” between groups can be apreciate.
Knowing what we know about the way calls are handled, I doubt there’s any way to prevent this. Your call is being moved from one feature to another (even though they are the same feature) so I doubt there’s anything you can do using this particular inbound call structure,
