> When asterisk receive a SIP call in SLIN16 codec and have to convert it to SLIN32, there is a degradation of sound quality at the places where we have voice saturation.
> There is a sign inversion which creates a bad voice quality.
> The same issue is present when converting a SLIN16 to SLIN32 format from the CLI interface.
