Some of the patents expire but nobody will know for a long time if there are any extra ones lurking in the bushes.

As far as the FS implementation, there are no current plans to change anything yet.

The good news is FreeSWITCH is a massive software project and its free, so the $10 for g729 is nothing in comparison.

Hi all,

So I fell down the Google rabbit hole this weekend - the subject of my curiosity: US Patent No. 5,920,8531

This patent has a priority/filing date of August 23, 1996, which would imply that the g729 is in the open next month. Is this accurate? Am I missing another patent that keeps this behind the commercial pay wall?

I'm asking b/c I'd obviously rather not license channels and find out it was unnecessary a month later.

Max
