Attempting to investigate failed call back reports

[Tarvin]

Hi All,

One of our customers has reported multiple call back failures today, and I am just wondering what my options are for investigating why they failed? The event log is not very verbose, and when I tried to search through things like QUeueManager.log, 3CX QueueManager.track, I was unable to find what I was looking for.

Thanks in advance,
Tarvin.
