Is MultiCarrier operation possible with the UmTRX in combination either OsmoBTS?
I'm not sure I understand this question. It does not seem to have anything to do with OpenBSC so probably you should ask it elsewhere.
On another note, is it possible for the outbound MNCC interface to pass call control to a standard SIP softswitch (kamaillio?) without going through LCR?
Not unless a standard SIP softswitch implements support for the OpenBSC MNCC interface. I don't think that they will. Why don't you just use LCR? It works fine. If you are determined not to learn anything on your own you can use http://stuge.se/lcr.txt for cheating.
