Yes.
See [[Category:Calling Features]] on the wiki.

There are 2 D/A, 2 A/D flexibly routed, and one D/A that is dedicated to 
the earpiece.

About the only limitation is that you can't do things that would require 
more IO sources than are available.
For example, playing stereo MP3, and acting as voicemail/answerphone may 
not be possible.
(It'd have to drop to mono).
