MeetMe functionality questions

I’m interested in creating a bridge for our company and sister companies to use for audio conferencing. I found Asterisk and am liking what I see here. My requirements are pretty basic but here they are. Can someone comment on the ability to do this?
I would need to ability to have at least 2 maybe 3 conferences going at once.
I need them to be password protected (pins) with the conference not starting until the host logs on.
Is the sound quality better over a T1 or do analog lines work fine?
Can I get detail reporting on usage?
