We're happy to announce the next incarnation of RetroNetCall, the retronetworking oriented spin-off of OsmoDevCall

This time, laforge (and maybe some others) will give a tour of divf, the central office of the OCTOI network based on yate + dahdi-trunkdev

We'll look into how subscriber E1 terminate in osmo-e1d + dahid-trunkdev, how that feeds into yate, how the routing/dialplan works, as well as the new SS7/ISUP interconnects to the two EWSD.

When: Wednesday, December 6, 2023 from 20:00 CET

Where: https://osmocom.org/RetroNetCall (Big Blue Button of https://franken.de/)

The official Osmocom binary packages will not be built anymore for the following distributions starting at 2024-02:

• Raspberry Pi OS 64-bit (use Debian_12 etc. instead)

• openSUSE 15.4 (openSUSE Tumbleweed feed is available)
• Debian Testing (Debian Unstable and 12-10 feeds are available)

For Raspberry Pi OS 64-bit users, make sure to adjust your /etc/apt/sources.list.d as described here to switch to a Debian aarch64 feed.
