i have found mon bcms sk 1 to show a realtime (well updated every 10 seconds) view of what is happening in the skill.
We do have a queueing step in the loop, and believe it or not, it was not a phantom call, I listened to the call recording from it, all they got was a rining tone despite the fact we have hold music set up.
Cheers for the response so far.
