Now I understand better what you want.

> I did not mean to switch to a different codec, but to set the quality parameters for the codec, like:
> 
> pjmedia_codec_speex_init: quality (0-10, default=8) & complexity (1-10, default=2)
> 
> An experiment found with 8KHz:
> - quality 2 => bitrate 5.9 Kbps  
> - quality 3 and 4 => bitrate 8 Kbps
> - quality 5 and 6 => bitrate 11 Kbps
> - quality 7 and 8 => bitrate 15 Kbps
> - quality 9 => bitrate 18.2 Kbps
> 
> I want to lower quality and increase complexity.
