Usually in a callcenter installation, you have more queues in which a call can pass through if it isn't answered by the first queue. And a queue in a dialplan can have more than one failover
So my suggestion is to have a visualization of failover's statistics.
For example, something like this:
QUEUE 1000
Timeouts to queue 1010: 45
Timeouts to queue 1011: 21
Timeouts to queue 1012: 10
Timeouts to queue 1013: 37
