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.

Virus Removal Service

Jaytag Computer are experts at removing viruses. In fact, in most cases we can clear up a virus infection within less than an hour – without losing any of your data.

A virus infection can stop you working dead in your tracks – you may find that searches on Google are redirected, your internet access is disabled, or your anti-virus program stops working.

If you are infected, there is a real risk that the data on your computer could be stolen or even held to ransom. If you think you are infected, stop using your computer immediately.

How we remove an infection

We use a number of industry standard tools like Combofix, HijackThis! and Super Anti-Spyware to check your system for signs of virus infection. If a virus is found, it is removed immediately.

Setup to shared printer from Mac OS 10.6 or newer

When trying to link to a Windows Vista, 7 or 8 shared printer from Mac OS 10.6 or newer, you may find that the printer gives this error message. Essentially, SMB printing from CUPS (the Mac OS printing system) seems broken – it does not pass along the correct user name and password (even when entered manually).

The solution is quite long winded… Firstly, ensure that the printer is shared on the Windows machine, with a share name with no spaces. (i.e. not “Canon IP 6700D”, but “CanonIP6”)
