Just a small question: I did a bit of patent research on G.729 and at
a rather superficial skim, it looks like the *encoding* stuff is patented,
but not the *decoding*.

This caught my interest, so I did some reading. Unfortunately, it looks like that isn't the case :(

"Is the G.729 Consortium License only required when the ITU-T G.729 standard is used for encoding signal ? No. The license is required for both encoding and decoding voice signal."

There has to be same way to provide at least a framework for supporting G.729 though. Maybe some way to use those codec licenses they sell for VoIP boxes in Wireshark if the user really wants to and pays for the license? I know that gets hairy too, but Asterisk seems to pull it off.
