> For example you want to create outgoing channel and play some file for tests
> You run something like 
> asterisk>  channel originate Local/s at contextA application Playback file_wav16 
> and you listen poor voice quality with compare of incoming call to context which do Playback( file_wav16)
> core show channel report what outgoing SIP channel created in contextA  have native format slin16 and have no recode, but not optimized Local channels report something like:
> side 1
>   NativeFormats: (slin)
>     WriteFormat: slin16
>      ReadFormat: slin
>  WriteTranscode: Yes (slin at 16000)->(slin at 8000)
> and for side 2
>   NativeFormats: (slin)
>     WriteFormat: slin16
>      ReadFormat: slin16
>  WriteTranscode: Yes (slin at 16000)->(slin at 8000)
>   ReadTranscode: Yes (slin at 8000)->(slin at 16000)
> also resampling looks very bad and generates a large distortion for powerful signals
