Do you know which version of libosmocore that branch
worked with? I have
tried it with both the master branch and the fairwaves/master-rebase branch
and neither one compiled. I also tried rebasing the
fairwaves/master-rebase onto master again. This at least builds but it
looks like osmo-nitb is sending a different version of SUP than what
libosmocore is expecting and so it can't decode it. The function in
libosmocore that seems to do the decoding is osmo_gsup_decode in gsup.c
I have seen references to be SUP and GSUP in the code. Are these two
different protocols or are they the same thing? Also, are they specified
anywhere other than in the code?

Hi Rowan,
A more recent version of this work is a part of the
fairwaves/master-rebase branch. It has implementation of exporting
USSD (and any other SS for that matter) over a SUP socket and an
external utility to decode/encode them and convert to/from SIP+XML
similar to defined in the IMS standard.
We're currently using this code to implement external USSD services
like a balance check from a billing system and also to forward SS and
USSD to MAP/Sigtran. So I think the code should work well for you.
If you find this code useful, we would greatly appreciate any help in
merging this code into master. We intend to eventually merge this into
master, but it requires some cleanup before it could be submitted for
a review and given it's not a simple small change we've never had
enough time to do that so far :(

Hi,
I’ve been looking into getting ussd working with an external
application. I
found a branch from last year
(fairwaves/sup-ussd) that looks like it
has
implemented most of ussd sessions and possibly
communicates with an
external
application. Does anyone know if it was finished
or what still needs to
be
done?
I also found a python script called ussd_example.py which looks like it
is
supposed to act as a gateway and receive used
connections from openbsc.
Is
this correct and did it work or am I
misunderstanding its purpose?
Thanks!
