>                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-24589
>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Codecs/codec_g722
>    Affects Versions: 11.13.0
>         Environment: Linux
>            Reporter: Daniel Ammann
>            Assignee: Rusty Newton
>            Severity: Minor

> Translation path between silk codec and g722 reduces quality one-way.
> core show translation paths for g722 and silk16 show the following:
> {noformat}
> g722       To silk16    : (g722)->(slin)->(silk8|silk12|silk16|silk24)
> silk16     To g722      : (silk8|silk12|silk16|silk24)->(slin16)->(g722)
> {noformat}
> So one way is going via slin16 (good), but coming from g722 to silk16 is going via slin, which means a reduction of bandwidth and hence a reduction in audio quality. 
> According to ASTERISK-15637, this should not happen but it does
