[App_rpt-users] Echolink connection announcement Volume

[kk6ecm]

I know for a fact we are using the files in /var/lib/asterisk/sounds. My understanding is, /usr/src/ contains the original source files, and not used during operation. To use them, they need to be copied into /var/lib/asterisk/sounds.

Thanks,
Bob
