Searching with CouchDB in Python
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 […]
Bolting an SNMP Server and stats collection onto your existing Python projects.
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
Using KEMI to handle Kamailio SIP Routing in Python
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 […]
Connecting to RTPengine via Python
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 […]
Basic usage of a Python RTP library I wrote
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 […]

A new tool I’ve written to stream packets from one machine to another for analysis in real time.
Unstructured Supplementary Service Data or “USSD” is the stack used in Cellular Networks to offer interactive text based menus and systems to Subscribers. If you remember topping up your mobile phone credit via a text menu on your flip phone, there’s a good chance that was USSD*. For a period, USSD Services provided Sporting Scores, […]
