You have to use this version https://github.com/fairwaves/openbts-2.8 - testcall CLI command was removed from mainline due to some political issues. After you install it you can use testcall command to initiate call to given IMSI. A very thorough description of using it is available at http://www.syssec.rub.de/media/emma/arbeiten/2012/11/16/2011-10-04-Weber.pdf > Secondly - how i can input (enter) IMSI to mobile phone to make phone calls successfully.

In order to avoid manually editing each number/IMSI I'm afraid you've got to modify sipauthserve (or code which interacts with it). Although it's not that hard - I've modified it to avoid calls to sipathserve https://github.com/zabbal/openbts-p2.8 Also a little clarification - IMSI is normally written into SIM card. I think osmocom-bb allows to modify on the fly but I don't remember exact command :( Anyway, you can always use programmable SIM card to put any IMSI you like in there. -- best regards, Max, http://fairwaves.ru
