Is there any free g.729.1 implementation for asterisk? I want to use it for my
private use (dialing into inet->PSTN gateway), and I don't want (now) to buy
codec, as I don't know if I will be using this service in future (now I just
want to test it). Any solutions? Maybe even free-15day-trial of g.729.1
codec?
There *are* no software patents on G.729. However, there are a lot of
signal processing patents, and they are applicable everywhere. A lot of
people seem to have the strange idea that implementing a patented
techique on a CPU, instead of some other hardware, suddenly makes it not
a patent issue in many countries. WRONG! As long as the original patent
was not so narrow that is was only claimed to apply to a very specific
realisation of the technique, a software implementation is just as
patent encumbered as any other.
