This is an abbreviation of Open Source Software.

The sipX stuff uses the sipXtackLib and sipXmediaLib from Pingtel.

Well, AIX is probably not competing with MacOSX even though they run on 
similar processors now.  What you probably mean is IAX, which is yet another 
PBX signaling/transport protocol.  From what I can tell, the world is moving 
away from this direction, not towards it.  Asterisk's approach to SIP is to 
essentially map a subset of SIP onto IAX, impose extra restrictions, and let 
Asterisk mangle the data as it sees fit.  The signaling and media are forced 
along the same path, which may or may not be what you want, but you lose 
flexibility with respect to SIP.   The biggest reason you don't see more OSS 
developed with reSIP is its license.  I have a mostly-complete plugin for 
kopete to do presence and IM using resip with some stubs for voice calls.  I 
haven't made it available because parts of Kopete are GPL and reSIP's VOCAL 
license isn't GPL-compatible according to license@xxxxxxxx  This actually 
prevents KDE applications from being written with reSIP unless you have a Qt 
developer license, although I suspect Trolltech would be forgiving on this 
issue.

http://sofia-sip.sourceforge.net/  They haven't released anything yet, but 
what's in their CVS repository looks promising.and a few projects are using 
it.

For media, look into sipXmedia.
