Custom Trixbox work

We have a Trixbox phone system in our office. We would like some basic customizations on it. - convert all monitor recordings to MP3 - at a specific time, copy all of these records to a Windows share - enable SRTP or TLS (if possible) - enable the monitor directory to hold more and use more of the drive - an easy way to export our blacklist - an ISO of Trixbox that incoporates these items (if possible)
