Hi All,
Does anyone tried enabling the A5/1 Encryption using osmo-bsc and osmo-msc?
We are using an UPBOARD with the following elements; osmo-bsc, osmo-bts-trx and osmo-trx in it; and a NUC with osmo-hlr, osmo-msc, osmo-mgcp, and osmo-stp.
Both servers are using Ubuntu 16.04 OS.
We enabled the a5/1 encryption in both osmo-bsc and osmo-msc. Then provisioned the programmable SIM to osmo-hlr with aud2g comp128v1 auth.
OsmoHLR# subscriber imsi 515941234567890 show
ID: 9
IMSI: 515941234567890
MSISDN: 09271234567
2G auth: COMP128v1

We are not really sure what causes the LOCUP Reject.
Can anyone help us with this issue?
Attached are the configuration used during the testing and a trace taken during the testing.
