There are four possible causes for the "*" symbol in the reports:

1. Your report is considering a time period that starts or ends in the middle of a call. QueueMetrics is letting you know that the call is outside the time range. Change the time range to fix this.

2. The logs are incomplete. For some reason, Asterisk has written the logs wrong, they are missing or the logs are doubled. Using the Asterisk Unique ID, can you find the logs in the /var/log/asterisk/queue_log-... file?

3. The PBX is not logging the caller number. You can find this out in the queue_log file, like before.

4. The numbers are hidden due to the "Hide Numbers" feature: Hidden Numbers policy
