The G.729.1 "wideband" codec is starting to show a slight bit of traction. There is a possibility that Asterisk could support G.729.1 - would you use it or buy it if it was available? More importantly, does any equipment with which your systems currently exchange traffic support G.729.1? Currently, the number of devices supporting G.729.1 seems to be fairly limited and it may be an imbalanced decision to support a codec that nobody else uses.
If G.729.1 were to be offered as a codec for Asterisk by Digium, it would have to be as a commercial product, as the codec is patent- encumbered. Pricing and licensing terms are outside the scope of this discussion, but I would expect something like G.729. Of course, passthrough-mode (non-transcoding) would not require licensing with Asterisk and is outside of the scope of this question. Timing is also an unknown issue - there are obviously many other projects in the pipeline for the Digium engineering team to work on before this probably could be completed, even if the decision is made to pursue a development effort. Note that G.722 is free and already available, and may have similar MOS scores (but certainly not exactly similar) as that of G.729.1. Comparisons of G.729.1 and G.722 are left as exercises to the reader, or see the excellent presentation below which is quite enlightening. Your opinions are welcome on the topic!

I'll also apologize for what is a post about issues that are not "open-source", but it seems that within Digium I'm probably the most appropriate person to canvass the community on this particular question, as it involves gauging the general thinking of the VoIP community and is not merely a Digium-only concern.] JT --- John Todd email:jt...@digium.com Digium, Inc. | Asterisk Open Source Community Director 445 Jan Davis Drive NW - Huntsville AL 35806 - USA direct: +1-256-428-6083 http://www.digium.com/ _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
