I've officially given up on AMR, due to it's licensing issues and sketchy supports for my mobile clients. I am looking for new options now as CsipSimple has a new codec pack supporting G.726.1, opus and codec2. Which do you think would perform best on mobile networks? And which has FS support for transcoding as well?
I think you means G.722.1 and G.726, rather than G.726. G.726 is narrowband and fairly high bit rate. Its not the greatest choice when you have packet loss. G.722.1 is wideband and fairly high bit rate. Its not the greatest choice when you have packet loss. codec2 is very low bit rate, which is good for some mobile users. The quality is good for the bit rate, but you can't expect high quality at such low bit rates. opus has lots of choices to trade off quality and bit rate. Its rather new, so not that widely supported, but it should become big over the next year or two. Steve
