Have you seen - http://osmocom.org http://osmocom.org I had followed the OpenGGSN project for a while, which is now under this umbrella of open source telco projects. Some cool things there, I've used a few for some basic testing however I'm not sure if anyone is actually using them in any kind of production network. From my previous experience most seemed to work, but did miss some fairly basic/standard features if you were comparing to an off the shelf box.
