![]() While testing, you may find out that making an emergency call is rejected with cause 5 (illegal ME), because emergency facilities in some countries like to reject calls without knowing the subscriber. An emergency IMSI can be defined via VTY, so it is possible to make calls with that IMSI, even without the SIM, because authentication is not applicable during emergency call establishment. All the information above, I received from the freely available 3GPP TS 04.08. See NOTE at sub clause 4.5.1.5. |
