No, I think you have some conceptual misunderstanding about radio
technology in general.

In your subject you ask if OsmocomBB can work as USRP:
This is wrong, as OsmocomBB is a protocol stack and radio driver, and the USRP
is hardware.  How can some software work as hardware?

In the body of your mail you ask if the C123 can act as USRP:
No. The USRP is a wide-band software defined radio, and the Calypso/Iota/Rita
design implements a more traditional narrow-band zero-if transceiver with a DSP
in the baseband.

Nevertheless, you can use both hardware design to receive and transmit GSM
signals.  But this is very far from what you ask by "one device working like
the other"
