Hi!

Yes.

I use transceiver  program from *jolly/testing* branch and

Stop doing this mix. The firmware from one branch you use incompatible with
host software form another. Use one branch only!
It looks like you have a new toolchain "gnu-arm-build.3.sh". The firmware
images from this branches works better if it's compiled with older
toolchain version.
Try to use
http://bb.osmocom.org/trac/attachment/wiki/GnuArmToolchain/gnu-arm-build.2.sh
or https://github.com/axilirator/gnu-arm-installer.

I know that Calypso BTS support only one timeslot.

Using two phones you will be able to serve two timeslots.

Follow this guide I recently wrote:
http://bb.osmocom.org/trac/wiki/Tutorials/CalypsoBTS
http://openbsc.osmocom.org/trac/wiki/SDR_OsmoTRX_network_from_scratch is
outdated.

С наилучшими пожеланиями,
Яницкий Вадим.
