Firstly, you need to check that you can successfully play files
outside of the AGI environment. Replace the AGI command with:

same => n,Playback(welcome)

If that doesn't work, the problem is nothing to do with AGI.

However, I think what else is happening is that your AGI script is
sending the STREAM FILE command and then immediately exiting. This goes
back to the dialplan and executes a hangup when only a tiny fraction of
the welcome file has been played. You could test this theory in two
different ways, as I'm not sure whether it's the exiting of the AGI or
the subsequent hangup that is aborting the playback.

a) Put a "sleep 5" in your agitest.sh after the echo. As others have
said, you should really use a proper library that reads responses to
AGI commands, but for testing, a sleep will keep the AGI script alive
while the message plays.

b) Put a "same => n,Wait(5)" after the AGI command. If the AGI leaves
the message playing, this would give it some time to play before you
hang up the line.

Hope this helps!
