Same here. I'm in training right now and have never been asked to give up my number. In fact, I'm still employed at my old airline until Oct 1 when my furlough becomes effective. When I was given the job offer at Compass the guy that called me told me that I could keep working at my old job while I'm doing the homestudy (which I'm doing). Everyone in my class is furloughed and none of us have been asked to give up our old airline seniority as far as I know.
