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. -- best regards, Max, http://fairwaves.ru

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 Well, sipauthserv uses sqlite.db which maps IMSI to phone number. If you edit it to make phone number == IMSI you can call using it. 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
