Libpython3.11 problems with Kamailio on Ubuntu 22.04
I run Ubuntu on my desktop and I mess with Kamailio a lot. Recently I was doing some work with KEMI using Python, but installing the latest versions of Kamailio from the Debian Repos for Kamailio wasn’t working. The following packages have unmet dependencies: kamailio-python3-modules : Depends: libpython3.11 (>= 3.11.0) but 3.11.0~rc1-1~22.04 is to be … Continue reading Libpython3.11 problems with Kamailio on Ubuntu 22.04

Telephony binary-coded decimal (TBCD) in Python with Examples
Chances are if you’re reading this, you’re trying to work out what Telephony Binary-Coded Decimal encoding is. I got you. Again I found myself staring at encoding trying to guess how it worked, reading references that looped into other references, in this case I was encoding MSISDN AVPs in Diameter. How to Encode a number … Continue reading Telephony binary-coded decimal (TBCD) in Python with Examples

Open5GS Python Library / API
A while ago I wrote a Python library for interfacing Open5GS HSS to Python. The Open5GS HSS uses a MongoDB backend, so the library is just running formatted Mongo queries. You can create, edit and delete subscribers in the HSS, along with modifying any parameters you can from the WebUI. Take a look: https://github.com/open5gs/open5gs/tree/master/misc/db/python

Open5Gs- Python HSS Interface
Note: NextEPC the Open Source project rebranded as Open5Gs in 2019 due to a naming issue. The remaining software called NextEPC is a branch of an old version of Open5Gs. This post was written before the rebranding. I’ve been working for some time on Private LTE networks, the packet core I’m using is NextEPC, it’s … Continue reading Open5Gs- Python HSS Interface

PyHSS – Python 3GPP LTE Home Subscriber Server
I recently started working on an issue that I’d seen was to do with the HSS response to the MME on an Update Location Answer. I took some Wireshark traces of a connection from the MME to the HSS, and compared that to a trace from a different HSS. (Amarisoft EPC/HSS) The Update Location Answer … Continue reading PyHSS – Python 3GPP LTE Home Subscriber Server

SCTP in Python
I’ve written in the past about SCTP – Stream Control Transmission Protocol, talking about it’s advantages and how to implement it in Kamailio. If you’d like to write your own software using SCTP there’s a fantastic SCTP sockets library from P1 Security that makes this easy as any other socket programming. Take a look at … Continue reading SCTP in Python
Kamailio Bytes: KEMI and UAC Module – Event Route
The UAC module is super handy for creating and sending SIP requests from Kamailio. It could be triggered via HTTP requests using xHTTP, other SIP messages or on a scheduled basis like with Rtimer. More and more I’ve been using KEMI to allow me to write Python based Kamailio dialplans, do to all sorts of … Continue reading Kamailio Bytes: KEMI and UAC Module – Event Route
It’s not Rocket Science – Tracking performance of OneWeb terminals
Last year we deployed some Hughes HL1120W OneWeb terminals in one of the remote cellular networks we support. Unfortunately it was failing to meet our expectations in terms of performance and reliability – We were seeing multiple dropouts every few hours, for between 30 seconds and ~3 minutes at a time, and while our reseller … Continue reading It’s not Rocket Science – Tracking performance of OneWeb terminals
Automatic Cell Planning with Atoll: Site Selection
One of the really neat features about using automated RF planning tools like Forsk Atoll is you’re able to get it to automatically try out tweaks and look at how that impacts performance. In the past you’d adjust something, run the simulation again, look at the results and compare to what you had before, Atoll’s … Continue reading Automatic Cell Planning with Atoll: Site Selection
CGrateS in Baby Steps – Part 5 – Events, Agents & Subsystems
Up until this point in the series, I’ve tried to hide all the complexity of CGrateS, so people following along can see some progress and feel like they’re making it somewhere with CGrateS, but it’s time to tear off the plaster and talk about the actual concepts, about what’s under the hood, and how all … Continue reading CGrateS in Baby Steps – Part 5 – Events, Agents & Subsystems
