Music on Hold version version 126.96.36.199 does not work with SoX 14.4.0 (Debian 7/wheezy)
When uploading a file to the server, SoX can not do “resamle -ql”.
Format commands in SoX v.14 changed to use the effect of
"rate" instead of “resamle”.
In fact, in the version of SoX 14.4.1 returned using the effect of “resamle” as an alias to the effect of “rate”. If anyone has a problem with “resamle” in the module Music on Hold, in the file - page.music.php, enough to change all that indicates
" resamle -ql" on " rate -ql"
