Dear Harald,

just wanna give report what I tests.

I test calls and when I picked up always hang up and paging fail for the first call.

sometimes osmo-mgw having this fail:
0180202124344842 DLMGCP <0011> mgcp_msg.c:262 Addressing virtual trunk without prefix (deprecated), please use rtpbridge/: '1@mgw'

20180202124344842 DLMGCP <0011> mgcp_msg.c:64 Generated response: line #00: 515 119 FAIL

but I think my configuration for osmo-mgw -c ~/osmo/osmo-mgw-for-msc.cfg has wrong cause I found this:
20180202115457644 DRTP <0000> mgcp_network.c:833 endpoint:0x1 data from wrong address: 127.0.0.1, expected: 0.0.0.0

I will try to look what may cause the connection hang up for my problem.

Thanks,

DUO

Dear Harald,
sorry for the authentication matter,
I got the solution now, I need to set encryption to a5 0 on the config.

Thanks for lightneing up before.

btw,
I try to make call but cannot hear the voices. will try this again and again.

Dear Harald,
thank you for explanation, I really appreciate it.

So, osmo-hlr now need authentication for connect to the network? so we cannot attach IMSI without the ki?

if Im not wrong I need to set disable it on the configuration?
location updating reject cause 13
encryption a5 1
authentication optional

on this authentication line need to change? I try do change to authentication disable, but not work. I believe I have wrong understanding here.

Im using for 2g network. as far I know only for 3g network you need ki right?

Hope some feedback. Thank you.

regards,
DUO

the error is quite clear: You have only an IMSI in your HLR, but no authentication
tokens (key material) for cryptographic authentication.

If at the same time you have configured your network to perform authentication (i.e.
not explicitly disabled it), then this will of course result in an error.

Either you enter key data in the HLR for your SIM cards, or you disable authentication.

The BSC has nothing to do with it. Your error is in OsmoMSC or OsmoHLR configuration.
