Information discrepancy between two reports...

[cursor]

I have a system running Asterisk 1.4.21.2 and Queuemetrics 1.4.7.1 on a Gentoo server.  Everything seems to be running fine but today we noticed that two reports have different information.  If I select the Last 7 Days and go to the Answered tab it says that one of my agents received 176 calls:

Montserrat Cruz     176      33.9%

But when I got to the Att. tab it says that the agent only has taken 74 calls:

Montserrat Cruz      0     -      0:00        74     0:43      53:25   

Why is there a difference in the number of calls taken?

[QueueMetrics]

It's two distinct pieces of information:
- the total number of calls taken is 176.
- the number of "attempts" seen in the log to ring the agent is lower. This means that the attempt logging is somewhat incomplete (attempts are not logged for every call). Anyway you care about attempts as much as they show "lost" attempts, so it's not a big problem. I think that version 1.5. should have a logic in the analyzer to assume an attempt event if it's not logged.
