[asterisk-users] SHELL function strangeness

[Julien Claassen]

Greetings!
   I have got a "systematic" problem with the SHELL function. Consider this 
dialplan snippet:
*** CUT ***
exten => NUM,1,Set(myreturn=${SHELL(ast_picker sound_file)})
exten => NUM,2,Answer()
exten => NUM,3,GotoIf($[${myreturn} = 0]?4:6)
[...]
*** CUT ***
   ast_picker does simultaneously play a sound_file and wait for input from a 
socket. If input comes or timeout expires, it sends a kill -15 signal to the 
player.
   If I start ast_picker from the linux shell prompt the player stops 
immediately if one of the conditions arrive. If I start it from the dialplan, 
like seen above, the player continues to the end of the file.
   Why does this happen? Is there anything to guard myself against it?
   If it would be helpful, I'd gladly upload the code for ast_picker, it's 
still very small.
   Please help me try figuring out what's wrong here or which extra condition I 
missed in dialplan application execution.
   Kindest regards
         Julien
