CalypsoBTS and modern OsmoBSC

Dear colleagues,

I am trying to set up CalypsoBTS with the last version of OsmoNTIB and
branch jolly/testing (so using two phones).
I found that the manual from the main site is outdated.
It doesn't work with the config provided os I am trying to figure out how
to tune it manually.
If I understood it correct, I have to setup calypso bts as bts of type
nanoBTS, correct?
I can sync with commercial cell, I can run OsmoBSC and OsmoBTS but I still
cannot find my network from my personal phone in searching mode.

Could you please tell me what can be wrong?
I tried both GSM900 and DSC1800, different channels selected after RSSI
checking...
Both phones are w/o filter rework, they are motorola c113 and c113a.
In logs of osmo-bts I can see:

<0000> rsl.c:246 Tx RSL RF RESource INDication
<000b> trx_if.c:397 transceiver (phy0.0) rejected TRX command with
response: 'RSP SETTSC -1'
<0000> rsl.c:2353 (bts=0,trx=0,ts=0,ss=0) Rx RSL BCCH_INFO

In osmo-bsc log everything looks fine:

<001e> input/ipa.c:263 accept()ed new link from 127.0.0.1 to port 3003
