[Freeswitch-users] g729 patent expiration

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.
