Thanks a lot for all your helpful answers. It's *working*. For your information, current config is UHD v3.7.3 & OpenBTS v5 with a B200 rev 4 under Ubuntu 14.04 LTS. @Ralph the problem is now with Asterisk and libsqlite3odbc.so file not found, I saw you faced the same problem and tried your solution mentionned in this thread https://sourceforge.net/p/openbts/mailman/openbts-discuss/thread/000001cfd5b9$95352d70$bf9f8850$@schmid.xxx/ but it still doesn't find the file.
