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
