             Summary: Translation from g722 to silk16
                 Key: ASTERISK-24589
                 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
            Severity: Minor


Translation path between silk codec and g722 reduces quality one-way.

core show translation paths for g722 and silk16 show the following:

g722       To silk16    : (g722)->(slin)->(silk8|silk12|silk16|silk24)
silk16     To g722      : (silk8|silk12|silk16|silk24)->(slin16)->(g722)

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
