Outside the US you can't patent software or algorythms, and a codec is (usually) both of these, >>therefore not patentable outside the US.

Try looking up the EU patents related to any of the ETSI codecs, like GSM EFR, half rate, AMR, >>etc. If Fraunhoffer's patents can be challenged, they must have screwed up the way they >>worded them.
=========== Hello,
I think that the discussion has strayed from its original subject: the subject is WHERE is the library for the G723.1 codec in Asterisk.
There are many people/companies/organizations who need G723.1. Although apparently it's not a problem using a patented codec like G723.1 outside of the USA, most of us would gladly pay a reasonable per-channel fee for it's usage, like in the case of the G729 which Digium offers.
But since it is not available in this manner, I think it's only fair to provide the source code for compilation/usage at least outside of the US.
I know that quite a few Asterisk users have compiled G723.1 in their box. Like many others, I would like to have this code and be able to compile it in my box.
In fact, many of us would even pay a reasonable sum in order to have the code, if the people who already have it & use it in their boxes are not willing to share for free.
Regards, Randy Ackers.
