This is merely a historical archive of years 2008-2021, before the migration to mailman3.
A maintained and still updated list archive can be found at https://lists.osmocom.org/hyperkitty/list/OpenBSC@lists.osmocom.org/.
Jacob Erlbeck jerlbeck at sysmocom.deThis adds a simulation of the SGSN side of the Gbproxy. The VC is set
up correctly and several combinations of BSSGP messages are sent.
