That is fascinating.  I did some research.

I'd say the open source version of G.729 is not viable for most
with a based entry fee of US$15K.  Best to find a licensed version
at a fraction of the cost.

Looking at the licensee list on Sipro's website tells me the G.729
patent is accepted throughout most of the economic world.

Are you paying for use or are you non-commercial?

Can you provide a link to this guidance? 

I found this in Intel's G.729 sample download EULA:

# ADDITIONAL LICENSES: Licensee's use or implementation of the Materials
# may require additional licenses, including but not limited to
# copyright and patent licenses from various entities including Intel.
# Should any such additional copyright, patent or other licenses be
# required, Intel expects that Licensee will and Licensee agrees to
# obtain any such licenses at Licensee's own expense. Licensee is solely
# responsible for obtaining any such licenses and the copyright licenses
# granted in herein are conditioned on Licensee obtaining such
# additional licenses.
