Sebastian Komorowski bajtelo at o2.plI 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?
