Hi Harald,
Thanks. The most important part for any kind of
debugging however is
always the pcap data of the A-bis and A interfaces, which are
unfortunately not provided. If possible, please re-run.
I just made another run and got the pcap:
https://www.freecalypso.org/members/falcon/osmo-cni/session2.pcap
I ran tcpdump with the following filter script:
tcp port 3002 or
tcp port 3003 or
udp port 2427 or
udp port 4729 or
proto 132
which should have captured Abis between OsmoBSC and nanoBTS, SCTP
carrying A, MGCP and GSMTAP. I also configured gsmtap logging in
OsmoMSC and OsmoBSC for this run - are there any more components that
need to have gsmtap logging enabled? I started logging after all of
OsmoCNI processes were up and running (I used vty to enable gsmtap
logging without saving it), but before I connected the PoE cable to
the nanoBTS - thus everything from nanoBTS power-up onward should be
in the log. Once nanoBTS booted up and started transmitting, I
registered two phones and dialed a call from 3302 to 3301. The call
failed exactly like before.
