Anton Gorbachev antgorka at gmail.comDear developers, Sorry for the previous question. I found that the solution is simple. The bug described here http://cgit.osmocom.org/osmocom-bb/commit/?id=a903b3c1ee27047c79728b18ff6340d23d1aad2e isn't fixed in branch jolly/testing I am using for calypsoBTS. So all I needed is just implement the fix and recompile from sources.
