I expropriated the right to rip Daniel's disclamer for use in my
email too..

DISCLAIMER:
You might have to pay royalty fees to the G.729 patent holders for using
their algorithm.

For easier testing I prepared codec_g729.so binaries and associated
libraries and put them on the web:

I wouldn't do that, if I were you. Distributing the source code for 
educational and evaluation purposes won't get anyone into trouble with 
the patent issues. I think (not sure) that Intel's copyright on the code 
is OK, since Daniel is distributing only patches to the original. As 
soon as you make binaries you are on shaky legal ground.

If you want to make things easier try to polish the install process to 
make it more idiot resistant.

I use Digium's Licensed Codec and I have no problems in routing calls to
either E1 or T1 interfaces.
But ...beware of the Pitfalls in using non-standard G729 Codecs.

I used a couple of sets before and here are the problems I found (I have not
used Daniels codec though):
1) Calls are too noisy and not at all readable
2) Calls disconnect as soon as connect
3) Calls required re-invite
4) Connectivity Timeouts
5) Authentication failures
6) E1 Gateways cannot decipher the calls

I have gone back to my limited user Digium License from the free G729 and I
could not be happier.

I will give Daniels' codec a try if  more people confirm (mainly those who
have successfully ran it on Fedora Core2) that this hack really works.
