[Asterisk-Users] dial script, send variable problem??

[Atuc]

hallo,

i trying to dial with a python script via the manager interface, it works 
ok but i would like to send a soud file name as a variable to the dialplan, 
so that i can call a number and send it a different soundfile i choose in 
my pyton script.

the problem is, that the * dials correct and sends a sound but only if its 
hardcodet, the variable my script sends will not bee seen in the dialplan?

how is it possibe to send a variable via a callscript to an extention?

thanks,
alexander

...... python code ...

sound="feature-not-avail-line"

s.send('Action: Originate\r\n')
s.send('Channel: IAX2/guest at snmdir.ath.cx/501\r\n')
s.send('Context: outboundmsg\r\n')
s.send('Extention: s\r\n')
s.send('Priority: 1\r\n\r\n')
s.send('RetryTime: 300\r\n')
s.send('WaitTime: 45\r\n')
#s.send(('Variable: snd=%s\r\n') % (sound))
s.send(('SetVar: snd=%s\r\n') % (sound))

// extentions.conf
; callgen test
[outboundmsg]
exten => s,1,DigitTimeout,5
exten => s,2,ResponseTimeout,10
exten => s,3,Answer
