This requires a wireshark with support for passing the new gsmtap V5 format into the existing wireshark dissectors for V5.
osmo-v5 - Osmocom implementation of ETSI/ITU V5 interface
This is a repository containing very early work-in-progress code implementing the ETSI/ITU V5 interface as specified in ITU-T G.964 + G.965.
V5 is an interface spoken between digital telephone exchange and its [remote] access network (multiplexers + concentrators of subscriber access lines).
For some general intro into V5, you might find the following OsmoDevCall recording interesting: https://media.ccc.de/v/osmodevcall-20211228-laforge-retro-isdn-v5
Initial development was done just using the spec as reference; from 09/2022 onwards a Nokia EKSOS N20 became the primary target.
You can clone from the official libosmocore.git repository using
git clone https://gitea.osmocom.org/laforge/osmo-v5
There is a web interface at https://gitea.osmocom.org/laforge/osmo-v5
