[asterisk-dev] G.729.1 - any interest?

[Dmitry Andrianov]

Did I miss something? Is Asterisk capable of handling 16KHz audio already? Can it mix 16KHz streams in the meetme rooms? Can it downsample them to 8kHz for Zap channels?

Who needs 16khz codec if the rest of the system cannot do anything about it?

Dear Kevin Fleming,
That what I said: G729.1 is a 50 7000kHz codec so a wideband.
I am requesting an ultra wideband instead of a wideband.

Best regards,
Stéphane Van Geystelen

7KHz is not ultra-wideband, it's wideband. There are already wideband
codecs out there, including G.722, G.722.1 and AMR-WB, to name a few.
There are also ultra-wideband codecs (16KHz bandwidth) including G.722.1C.
