Quick intro to setting up Wireguard interfaces in Mirktok’s RouterOS.
Through fs_cli you can orignate calls from FreeSWITCH. At the CLI you can use the originate command to start a call, this can be used for everything from scheduled wake up calls, outbound call centers, to war dialing. For example, what I’m using: originate sofia/external/[email protected]:5061 61399999995 XML default originate is the command on the FS_CLI […]
A look at attack vectors the NRF opens up in #5G Core networks, and the mitigations recommended by 3GPP.

How GTP is extended in 5G Core Networks to support extra QoS functionality like Reflective QoS and Delay Indicators
Another deep dive into deceptively simple seeming functions to do with SMS.
5GC includes native support for framed-routing.
A great new feature of #5G Core Networks is Reflective QoS – Where QoS of the traffic coming to a UE is reflected on the QoS coming out.
Relocating vast numbers of subscriber lines is something to be avoided. In 1929 Indiana Bell realized they needed a larger telephone exchange (“CO” to use the US term) to meet growing demand, and while there was vacant land around the current building, it wasn’t large enough to build on with the current building slap-dab in […]
Using the Rtimer module and UAC to be annoying, or very useful.
The first SMS was sent in 1993, and all these years later as 5G rolls out, we’re still supporting it.
There’s no such thing as a free lunch, and 5G is the same – services running through a 5G Standalone core need to be billed. In 5G Core Networks, the SMF (Session Management Function) reaches out to the CHF (Charging Function) to perform online charging, via the Nchf_ConvergedCharging Service Based Interface (aka reference point). Like […]
A look at Centralized vs DeCentralized Online Charging with the aid of sugar.
After headaches importing elevation (DEM) data into Forsk Atoll, I found a better mechanism for converting them, I’d been having issues with as soon as the elevation passed 255 meters, resetting to 0 in the PNG as it didn’t understand values beyond this. I was able to open the elevation data in GlobalMapper (You can […]
