Norbertas Kremeris n.kremeris at live.comHello all, I have run into some problems while building and running osmo-nitb, osmo-bts-trx and osmo-trx on Ubuntu 16.04. I am trying to create a self-contained gsm network box. I have successfully built libosmocore, libosmo-abis, libosmo-netif, libosmo-sccp, openbsc, osmo-bts and osmo-trx all from git sources, and i am also using linux call router. All make checks pass corrently without issues. As for the SDR side, i am have the latest UHD, SoapySDR and SoapyUHD, and latest LimeSuite library for LimeSDR support. SMS send/receive works correctly without any issues. Calling, however, works neither with osmo-nitb as standalone, neither with osmo-nitb with -m parameter + LCR. when trying to call, the receiving phone rings, but when trying to answer it randomly either gets stuck and does not answer, drops the call instantly or actually takes the call (and the elapsed seconds counter starts counting), but all you can hear is random noises coming both from the calling and from receiving phones, while the calling phone still shows that the call has not been answered, as in still calling. this is the debug info from osmo-trx: <0000> rsl.c:606 (bts=0,trx=0,ts=2,ss=0) Tx CHAN ACT ACK <0011> lapd_core.c:920 Store content res.
