[asterisk-users] Asterisk 14 audio quality with remote files

Hello everyone,

I am using the Asterisk REST API in order to establish a call to an
endpoint and to send over a remote file (HTTP).
The issue is that I am experiencing an audio quality issue.
I have tried encoding the file differently, but everytime Asterisk is
cutting the audio frequencies above 4Khz.
The call is established with G.722 and the audio file is mono 16Khz 16 bit
sln16 extension.
What can I do to improve the sound quality? Is there any way to not have
asterisk cut the audio frequencies?

best regards
