I know that CalypsoBTS is not stable solution. But currently I am a

</span>I'm sorry to say that none of the branches you refer to are maintained<br>
by anyone at this point. It would be great if somebody interested in<br>
that code (i.e. using it) could forward-port it onto current master.<br>
Now tat l1sap and osmo-bts-trx is in osmo-bts master, this should be<br>
relatively straight forward.<br>
<br>
It's really sad for us to see that people are continuing to use<br>
old/outdated non-master, rather than rebasing + submitting their changes<br>
for inclusion. It always makes me tempte to remove some of those<br>
branches from the repo, ort at least rename them to something like<br>
'outdated'.<br>
<br>
As you are the first person to report using the code to this list for<br>
quite some time, it would be great if you had some time to re-base, test<br>
and submit it.<br>
