Hi inode,
this list is about osmocom-bb, and not about the osmocom projects about networks-side gsm. OsmoTRX, OsmoBTS & Co are discussed on the openbsc@lists.osmocom.org mailing list. Please consider asking your questions there.

but from my understanding it support only GSM calls and SMS and GPRS is not implemented into the transceiver. I'm wrong or this part has not been implemented yet?
I have never used the "calypsobts" hack. But osmo-trx + osmo-bts-trx have support of voice, SMS and GRPS services.
As SMS is using the same signaling channels, this should definitely work even with the CalypsoBTS. For GPRS, you'd need to support the GPRS related coding schemes and an interface to OsmoPCU. Also, given that CalypsoBTS can only provide single (or two?) timeslot, there are a long list of reasons why it would not work straight-forward. But technically also possible to make work.
If needed to use a GPRS BTS can you suggest the best cheap SDR to use with OsmoBTS? (I saw BladeRF and LimeSDR but I was unable to understand if they are full supported via OsmoBTS)
Please raise this (and continue any related discussion) on the other mailing list.
