That sounds like they are trying for a similar arrangement Polycom has
with G.722.1. You can use G.722.1 royalty free, if you ask for a licence
first and comply with some simple conditions - mostly ensuring that you
properly follow the G.722.1 spec. It works well enough for most
purposes, though it conflicts with some free licences, and there have
been some disagreements. For example, Polycom said it was OK for
Freeswitch to be distributed with the source code for G.722.1 bundled.
It seems Digium believe Asterisk may not be distributed with the source
code for G.722.1.
