Description

3GPP LCLS allows the media stream of a call to remain locally at the BTS, if both legs of a call are within the same BTS. We should implement this in OsmoMSC, if not only to test the OsmoBSC side which we want to implement, too.

Shall I take this as well? Seems like next logical step to be able to test LCLS with actual hw.

Corresponding libosmocore changes are mostly merged, there're 4 more pending patches for OsmoMSC.
N. B: current implementation is only suitable for testing due to issues with CallRef handling by transactions. This part is going to be heavily changed by intra-BSC handover work.
