After some trials and tribulations, I think I got my OpenBSC+LCR+Asterisk compiles and working. The MS connects once I spoof the proper MCC/MNC for the foreign SIM I have (to ensure that no one else can connect within my area). Then when I try to make a test call to an asterisk extension, it give me the following:

Any assistance would be appreciated.
