[Freeswitch-users] Open Source MSC.

Hi everyone. I do know that this is the mailing list for FreeSwitch. But as I'm struggling finding anything (on Google etc.) about any open source MSC (HLR/AUC/SMSC/MMSC etc.) I'm trying here. I want to use FreeSwitch in a MVNO setup with a operator to make a proof-of-concept idea. But I need the MSC handling SIGTRAN and acts as HLR/AUC etc. I've looked at http://www.openimscore.org/ and http://www.mobicents.org, but I'm struggling figuring out there place in such setup. This is just for the proof-of-concept, so scale-ability, stability etc. is not as big a priority. Can anyone help me in the right direction? All help is appreciated!
