search for: stats_qstat

I have a server which I haven't installed that I have to maintain. This server uses MySQL, it has an asterisk database and in there some mysterious tables: stats_action, stats_agent, stats_callid, stats_config, stats_estados, stats_qstats, stats_queue, stats_queuexagent. I say mysterious because I don't have a clue about who is generating them. I did a grep for their names in /var, /root and /etc with no luck. Does anybody have any ideas what might be generating them, and populating them? Thanks. -- Jos? Pablo Fern?ndez pab...
