Hi Aalto, Pau,
The problem is that your BTS<->BSC<->...
is failing.
I don't see any related packets in the captures, neither RSL nor OML...
However, I see an obvious issue - IPA unit-id mismatch:
# This is the unit id that has to match the BTS
configuration
ip.access unit_id 1800 0
vs
ipa unit-id 6969 0
Are you using some configuration examples? If so, where are they from?
Also, are you sure that osmo-bsc is actually running on 192.168.122.1?
With best regards,
Vadim Yanitskiy.
