CGRates in Baby Steps – Part 2 – Introduction to the CGrates API
Linking FreeSWITCH and CGrates for realtime credit control and billing
A new tool I’ve written to stream packets from one machine to another for analysis in real time.
Ubuntu 20.04 repos have a fairly outdated release of Wireshark, and the other day when trying to open a packet capture I got the below error: After doing an apt-get update && apt-get upgrade wireshark, the version of Wireshark, and the issue remained. I have compiled Wireshark from source before, but it’s a real headache, […]
Getting started with CGrateS to bill for calls in a Telecom environment.
Unstructured Supplementary Service Data or “USSD” is the stack used in Cellular Networks to offer interactive text based menus and systems to Subscribers.

It is rather unstable, in that if it fails to dispatch to a Diameter peer, the whole thing comes crumbling down, […]

Introducing YAML based config files for defining how PyHSS should be setup
A Mikrotik is not a NAS. Or is it?
Thanks to some recent developments, PyHSS has had a major overhaul recently, and is getting better than ever, Some features that are almost ready for public release are: Config File Instead of having everything defined all over the place a single YAML config file is used to define how the HSS should function.

Bolting an SNMP Server and stats collection onto your existing Python projects.
It’s 2021, and everyone loves Containers; Docker & Kubernetes are changing how software is developed, deployed and scaled. And yet so much of the Telco world still uses bare metal servers and dedicated hardware for processing. So why not use Containers or VMs more for VoIP applications? Disclaimer – When I’m talking VoIP about VoIP […]
