add myself to the topic of CSFB with Osmocom + open5gs EPC


As OsmoDevCon could not be hosted in 2020 due to the Corona virus outbreak, and it seems it is unlikely we will be able to host one in 2021 either, we are announcing a new Osmo com Dev eloper Call is a new format of online meetings within the Osmocom community (originally discussed in #4928).

The formant serves two major purposes:

  1. technical presentations about osmocom relevant topics - ideally current/recent developments
    • can be pre-recorded to avoid any problems with technical setup, streaming, ...
      #*should ideally have a Q+A session at their initial "airing" during one OsmoDevCall
  2. unstructured supplementary social event (USSE)
    • random chat in audio (optionally video)
    • not recorded, obviously

The recording of the technical presentation should then be permanently made available (like the presentations of our prior OsmoCon / OsmoDevCon).

Not every OsmoDevCall would neccessarily need the two parts, but I think it would be great if we can make that happen. We could also have e.g. a two-weekly schedule for the USSE and a monthly schedule for the technical presentation.

We'd need somebody to volunteer to "manage" the "broadcast" side of this, preferably somebody with at least some prior exposure to online events (like the c3voc).


Friday evening, 8pm CET, every 2nd and 4th friday of the month

The first couple of events hence are:
  • February 26th, 2021
  • March 12th, 2021
  • March 26th, 2021

Venue / Platform

We are currently using infrastructure of KNF, a German non-profit internet organization of which laforge is a member.

The URL to join the meeting is

There currently is no password or authentication, we try to welcome anyone. If this turns out to be a problem, we might lock it down in the future, let's hope that's not required.
