I have installed osmo-bts-trx and osmo-trx-uhd on one machine (IP:
192.168.75.174), and on another machine, I installed osmo-bsc, osmo-msc,
and osmo-hlr (IP: 192.168.75.185). How should I set the IP addresses in
their configuration files?
in osmo-bts-trx:
osmotrx ip local ?
osmotrx ip remote ?
oml remote-ip ?
in osmo-trx-uhd
bind-ip ?
remote-ip ?
Also in bsc what config should be change?
Hello.

have installed osmo on 192.168.75.185 and also it work well and call
establised. but when I add sgs config in mme, It show this info:
[mme] INFO: sgsap client() [192.168.75.185]:29118
(../src/mme/sgsap-sctp.c:55)
[mme] INFO: VLR-SGs[192.168.75.185] connection refused!!!
(../src/mme/mme-sm.c:717)
In osmo-msc.cfg i add:
sgs
local-port 29118
local-ip 192.168.75.185
vlr-name vlr.msc001.mnc001.mcc001.3gppnetwork.org
end

Dear Harald,
I watched your excellent presentation on eSIMs and I have two
questions just to make sure I understand the situation correctly.
1. Both the eSIM profile and the SM-DP+ server's certificate has to be
signed by the GSMA in order to be able to provide eSIM services to
commercial handsets?
2. If the above is the case, that means we effectively lost control of
the SIM infra, as we always have to rely on 3rd party SM-DP+ and eSIM
profile providers who can provide the necessary signing for both the
eSIM profiles and the SM-DP+ server certs signed by GSMA?
Based on what you implied during the OsmoDevCall call about getting
certified, I am under the impression that Sysmocom will not be able to
provide nor eSIM profiles nor SM-DP+ services that can be used for
commercial handsets? If this is the case, can you kindly redirect me
to a vendor/provider who you have good experience with in this regard?
Much appreciate your help!
Regards,
Csaba
