Hi,

I have a somewhat off-topic issue about this codec thing.

If you look into the code you can see that it is only there for educational purposes and that the code is copyrighted and should check www.sipro.com before actually using it in any operational environment.

I have seen this codec item so many times and I wonder why people always are running in circles doing the same thing trying to use some sort of g729 implementation without paying for the license.

It is not that I like to pay for this stupid patented G729 license but everybody has to consider when using G729 in whatever software application that there is some 15k setup fee.

The real topic here is that g729 is necessary because some part of your setup requires g729 or g723 to achieve low bandwith consumption while the whole "old fashioned" telephone industry works with g711 g729 g723 and we still use this to terminate our PSTN traffic.( Not yet iLBC or GSM or speech or G726)

So in stead of discussing the implementation of G729 or G723 over and over again it is maybe time to form a workgroup that tries to achieve a transparent opensource replacement of mentioned codec's that can be used in whatever application.

After all VoIP is there to lower the cost of traditional Voice traffic and you might imagine that not everybody is happy with this. So do not forget the commercial influence on this subject.

You should expect that in this billion dollar VoIP industry this codec issue was taken care of long time ago but unfortunately it is not.

Sorry to bother you guys with this off topic item and keep on doing the excellent SER job.

Hi,

Intel has an open source code for g729. This sample supports the ITU-T G.729 Recommendation and Annexes A, B, D and E.

Someone has adapted this with *. http://www.readytechnology.co.uk/open/g729/

Is it possible to integrate this with sems?

Also Intel has other sample code for g723, g728 and g722.

Thanks, Richard
