Hi all! Following wiki I am trying to launch OpenBSC on CalypsoBTS (two OsmocomBB phones) with speech support.

I compiled libosmocore, libosmo-dsp, libosmo-abis and jolly/trx branch of OsmocomBB with transceiver support. Then I compiled opencore-amr, Sip-Sofia, oRTP for LCR. Then I compiled OpenBSC, OsmoBTS (with osmobts-trx) and LCR.

OsmoBTS configured to use two timeslots only (slotmask 1 1 0 0 0 0 0 0) and it uses TS0 as CCCH+SDCCH4 and TS1 as TCH/H. Here is some strings from my openbsc.cfg:

bts 0
  codec-support fr hr amr
  trx 0
    timeslot 0
      phys_chan_config CCCH+SDCCH4
      hopping enabled 0
    timeslot 1
      phys_chan_config TCH/H
      hopping enabled 0

When I use jolly/multi-trx branch of libosmo-abis, jolly/testing branch of OpenBSC and jolly/trx branch of OsmoBTS my network works very unstable. When I try to make voice call sometimes it falls with message "No resources for TCH/H". Russian language in SMS is not supported. I think it is because this branches are obsolete.

I tried to compile everything again but used master branches, and it worked much better! Now everything works as well. But when I call to 995 or 993 numbers of LCR I hear nothing. :(

In OpenBSC console I see:

What does it mean "TCH/F has not been served !! No prim for trx=0 ts=1 at fn=913770 to transmit."?

I tried to make phone<->phone call with and without LCR. I tried to switch between TCH/H and TCH/F and use different codecs: arm fr hr. But unfortunately there is no sound.
Can anyone help me?

Thanks a lot!
