FreePBX – convert WAV call recordings to MP3

One of our customers recently reported an interesting issue. They were running FreePBX on a machine with a very small amount of hard drive space. Usually, this would not be an issue, as FreePBX can be installed easily onto a small drive, even less than 10GB (I have a moment of reflection now, thinking that actually 10GB is massive!!)

In any case, when you start recording calls on a system, the free space is quickly eaten up.
Within FreePBX, there is no way to set the call recording to MP3, and as a result, large WAV files are created.

Using Ansible to update MikroTik routers

Administering a large installed base of MikroTik routers can be difficult. You can use The Dude, but this has not been updated in some time, and MikroTik have not made their long term intentions clear in relation to the continued development of the software.

We use Ansible internally to remotely configure machines, so it seemed a natural choice to update the firmware of the MikroTik routers we have installed.

Firstly, you need to generate an appropriate DSA SSH key.
