If you need this kind of monitoring, then there are probably better ways to take care of this and they are independent of Asterisk.<br>
<br>
What you could do is to tap any traffic in the background, e.g. with tcpdump using the -G option and automatically delete the files after a certain period, unless there is a reason to keep the data. The pcap trace would contain a lot of relevant information, even if the traffic is encrypted (like timing data). Depending on national or local laws this might be even a more serious crime than threatening a school. It could still be justified to tap the traffic, like it is for other public authorities, but you would have to find out yourself whether you are or the school is allowed to do this.<br>
<br>
Actually, I tend to think that it is the school's task to enforce a specific security and surveillance concept and this also applies particularly to their IT structure. You are certainly not in the position to decide whether you should monitor anything unless it is part of your contract.<br>
<br>
Besides this, it is easy to store any kind of information along with classical CDR data. Just search for "adaptive ODBC", or read the Asterisk book.<span class="HOEnZb"><font color="#888888"><br>
