No DAHDI modules on the system. Not starting

You need to retrieve the correct kernel-devel for the kernel of linux you are running, and remake DAHDI from source

SSH onto the machine and run:
uname -r

Note the kernel version.

then, google for kernel-devel (kernel version)
find a suitable download source (i.e. from rpm.pbone.net)

then on the machine
rpm -ivh ftp://ftp.is.co.za/mirror/centos/6.5/updates/x86_64/Packages/kernel-devel-2.6.32-431.1.2.0.1.el6.x86_64.rpm  Click here for more details..

Case Study – Router Upgrade – from 8Mbps to 200Mbps

We were approached by a client in central London to help with their internet connection. Although they had upgraded to Virgin Media’s 200MB/s DOCSIS3 service from a standard ADSL connection, they were still getting poor broadband speeds.

Old Hardware

As soon as we visited the site, the problem became apparent. They were using a Netgear FVS318v3 – this is a very out of date unit, that has a maximum throughput of 11.5Mbps. See the technical specifications here for a blast from the past: fvs318v3. Click here for more details..

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.

The solution? Convert them to MP3, and update the CDR database to reflect the changed filenames – so that if you wish to download the call recordings from the web UI, the links are correct.
