It looks like this is addressed in change 11139, however this was 3 months ago, and build date
of osmo-msc_1.2.0_armhf.deb seems to be nov-10, but it seems not in there.
Would the fix be in osmo-msc_1.2.0.140.1051c_armhf.deb ?

Hello,
I have recently started to deploy OpenBSC . Initially I hope to contribute to manuals and howtos
and with bug reports and testing. I have followed the suggested line, and installed everything from
binarys, which puts for instance osmo-msc at 1.2.0. The platform is Orange Pi Zero, and UHD / B100,
but will evolve to OPI Z + limesdr-mini.
I have encountered the "swapped address" bug reported some 3-4 months ago, but is there in
osmo-msc 1.2.0, i.e. resulting in one way audio, since the sdp is addressed to a byte reversed
address. Apart from that problem I have some minor stability issues (more later ).
so, my entry #1
Latest .deb packages have an issue with requesting the RTP stream for audio TO Mobile
