There is regarding the copyright on the code. The fact it is also patent
encumbered is a different issue.

Not true. He said it was a lab setup. It is totally legit to use patented
processes in an evaluation/lab environment.

Your comment about open source is irrelevant to performance, stability, and
security. WRT these criteria, I would be surprised if there is much of a
difference. The free software isn't locked to a mother board, so that might
count towards performance by some measures.

Now having said that. I agree once you leave the lab environment and decide
you need g.729, you will unfortunatly need a licence to keep using it.

The real question is: is there really any choice other than Digium for the
licence? Due to the dual licensing of the asterisk code, even if you could
license the codec elsewhere, you might be violating Digium's OSS license
when you don't but their commercial asterisk license.
