Hi Community,
Does anyone here tried to upgrade the your working OSMO environment to its latest version?
I have the experience where I upgraded my working osmo to the latest version and I have
encountering some problem between the connection of osmo-nitb and osmo-sip-connector. For
the latest sip connector update it will communicate the connection going to osmo-msc.
Since I don’t use the osmo-msc instead I am using the osmo-nitb for the standalone
project. Below is the error I have experiencing right now in the osmo-sip-connector and
osmo-nitb.

Hello Sonny,
thank you for such a detailed report.
Does anyone here tried to upgrade the your working
OSMO environment to its latest version?
I guess almost everybody (at least in development team) nowadays is
using the new CNI stack with separate components (BSC, MSC, HLR),
because osmo-nitb has been deprecated years ago. We don't really want
to look back all the time and keep compatibility layers for osmo-nitb
in other components. This means that you're mostly on your own with
osmo-nitb.
Since I don’t use the osmo-msc instead I am using the
osmo-nitb for the standalone project
I would still recommend you to use the new stack, since we have fixed
tons of bugs and implemented many new features. But if it's not
possible, you could try to downgrade osmo-sip-connector.
Alternatively, you could implement handling of the new MNCC protocol
version (6) in osmo-nitb. I believe it's just a few minutes of work,
basically: updating some structures and bumping protocol version in
the header file. Patches are welcome ;)
Good luck!
With best regards,
Vadim Yanitskiy.

Hi Vadim,
Thank you for the information. I just downgraded the version of my sip-connector just to
support the version of my osmo-nitb.
Regards,
Sonny

Sorry but - everyone is free to shoot themselves into the foot. If you
are using software that is abandoned,
deprecated and unmaintained for several years now (osmo-nitb), you
cannot expect any support for this by the community - particularny not
if you want to combine it a much more modern osmo-sip-connector.
Either you use ancient osmo-nitb with ancient lcr or osmo-sip-connector
(and no support), or you use a CNI based network with separate BSC, STP,
MGW, MSC, HLR, ... - which will also give you many years worth of
bugfixes.
Regards,
Harald

Sonny,
I had been thinking about dealing with this for sometime now, as Vadim
says, not a big job,
I had just wondered whether to "upgrade" the mncc support in osmo-nitb
or else to make a configuration variable in osmo-sip-connector for
"mncc-version" and make the new code dependent on that. Probably the
first option would be most acceptable as why burden the
osmo-sip-connector with code to support something obsolete? On the other
hand you add some code to osmo-nitb just to throw it away, (the nitb
won't use any of the new fields in the MNCC version 6.)
Partly I never did either, as I don't want to bother code reviewers with
supporting osmo-nitb.
I totally am with what Harald says, at the same time, it has kind of
annoyed me that we still publish packages for osmo-nitb and
osmo-sip-connector and that combination has not worked now for some time.
So, in the meantime, if you MUST use osmo-nitb, unless you still have a
package for your OS around, (check in your apt cache?) I'd suggesting
building osmo-sip-connector version 1.3. It's a fairly easy build.
If you really really have a pressing reason why you cannot move to the
new core network stack and you absolutely cannot find a solution, Tell
me something about your use case, either PM or here on the list, I can
help out one way or another.

Hi Keith,
Thank you for this. I just downgraded the osmo-sip-connector just to support the version
of osmo-nitb.
