Actually, unless they gave Digium different terms than the ones on
their web site, ilbc is unfortunately not gpl or lgpl compatable.

There is a clause that says you cannot use the code except to create
or decode iLBC bit streams, and said bit streams must be exactly the
same as what the reference code does.  That clause makes compatability
with the gpl, lgpl and some other floss licences¹ impossible.

Were they do follow Xiph's example and license the code and the
trademark under separate terms, freeing the code but requiring
the current license's bit-stream compatability to use the iLBC
trademark, things would be much better indeed.  We'd also be
able to improve the reference code's speed by adding support
for the various simd intruction sets, et al.
