Yeah, but that wouldn't fit in the box.
Anyway, the most commonly accepted definition of open-source would not
consider the iLBC codec to be open-source. See
http://opensource.org/docs/definition.php Section 3:
"The license must allow modifications and derived works, and must allow
them to be distributed under the same terms as the license of the
original software."
This license restricts modifications.
