Call-by-IMSI got to be supported by BTS, which is not normally the case, however
OpenBTS fork from Fairwaves have testcall function which does just that.

In general - mobile-terminated call can "by IMSI" because for mobile phone there's no
difference in how it was reached exactly_ as long as BTS exposes that functionlity.
For mobile originated calls I think it can be implemented on BTS side if you simply
use IMSI as a phone number in authentication db/sip backend of OpenBTS.
