[Asterisk-Users] Prices of g729 codec

[Cory Andrews]

Voiceage in Montreal is supposed to be working on an open source G.729A
codec, although it mentions only that they allow developers to freely use
their G.729(A) codec object code for non-commercial purposes.

Lots of good codec related info here

And it's not there because it is significantly more computationally
intensive than G.729 (I don't believe there is a fixed-point Speex
implementation either, although I could be wrong) so that means the hardware
cost for the ATA/phone/etc. goes up.
