The diff between this and master will probably need a lot of review and fixes. The current state does compile, but I expect pretty much everything to be broken now. Future development will reinstate proper functionality piecemeal. The first goal is to get basic signalling to work, then SMS. The voice control (RTP) is completely disabled now (see "#if BEFORE_MSCSPLIT") and will be fixed last AFAICT.
