error no audio "Gretting welcome"

when I receive a call from the outside, CallButler respond, but
you hear the "Gretting welcome" and the voices of the menu.
If I press 1 the call is sìtrsferita properly inside.
I tried on multiple computers, but it's all the same.
I tried it with mp3 and wav file but the result does not change.
The logs are correct
What can I do?
