hi sebastian,

in a traditional network it is not possible, as far as i know. also 
there is no number type for "imsi" defined, so if you use osmocombb, you 
can't. if you use openbsc, you can, if you make calls via MNCC 
interface, by setting IMSI instead of called number (in conjunction with 
LCR (linux-call-router) application, using a dial string like 
"imsi-xxxxxxxxxxxxxxx"). i used this for test calls.

best regards,

andreas
