(Afaik) Freeswitch is a distributor of binaries based on FFmpeg's and
Polycom's source code. Freeswitch also hosts Polycom's source code.

It appears to me that Freeswitch claims that while libg7221 is not a
Free library (and has a license incompatible with the GPL), it is
"open source" and can be distributed.

I still wonder what the difference between the libraries that are
only allowed to be used with a patent license is...

PS: In case this isn't obvious: We should of course improve our
existing related decoder instead of linking a non-free library. I
just believe that the used argumentation is surprisingly weak.

And I still wonder why the mentioned patch wasn't published for
interested parties...
