I'm sure that Asterisk will work with MSN's, just that I've never used 
them ;)

Check out www.telappliant.com - they sell a load of very cool stuff 
that works with Asterisk. I've used the AVM B1 cards, and the Eicon 
Diva cards - the Eicon's are slightly better in my opinion (nicer to 
work with/have hardware echo canceller) - problem is, Active ISDN cards 
aren't cheap :(
