No, this setting comes from the on-waves/bsc-master branch where the emergency calls are simply forwarded to the MSC and it is only about indicating that emergency calls are supported. To implement Emergency Calls in bsc_hack you might need to change the gsm0408 code of OpenBSC to handle the CM Service Request for emergency calls properly (e.g. check for a valid IMSI as of German regulations), and provide a 'dial plan' of where 110 should be forwarded to. E.g. it could make sense to have a small setting to forward 110 to a different mobile subscriber... If you have any specific implementation question, please feel free to ask.
