I have USRP with OpenBTS. I can now make phone calls from phone to phone i this two MS is connected to my BTS.
Can you explain more precisely how to make phone calls using IMSI and OpenBTS?
Secondly - how i can input (enter) IMSI to mobile phone to make phone calls successfully. Software in phones supports functions like this?

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.
