> Hi,
> I am using an agi (hereafter halvox.agi) program to automatically answer spoken questions. 
> halvox.agi  creates an output file named /tmp/file_out.wav16 
> extensions.conf :
> exten => 1000,1,NoOp()
> same =>    n,Answer()
> same =>    n(record),agi(halvox.agi,fr-FR)
> same =>	  n,Playback("/tmp/file_out", "#")
> same =>    n,Hangup()
> after the agi call the file Playback has poor sound quality. This really seems  to be related to the agi call since if I comment the line ";same =>    n(record),agi(halvox.agi,fr-FR)" then sound quality is good.
> Doesn't seem to be related to the file format either as I have tried different file format (sln, sln16, ...). I have also tried to run the Playback inside the agi script, same issue.
> Any clue why the agi call changes the way Playback behave ? Any help would be appreciated, thanks in anticipation,
>            Thierry
