[asterisk-users] Play announcement during Dial just once

[Roland o/d Akker]

Hi,

I would like to perform a Dial, and play an announce ment just once to 
the caller. Actually very much like the A parameter, but this plays the 
announcement to the callee instead of the caller.

I played around with MusicOnHold, for which I can specify a timeout, but 
it doesn't continue in the dialplan before it's done. So this didn't work:

exten => *92,1,Answer()
   same => n,Playback(sgn-u-bent-verbonden-met)
   same => n,MusicOnHold(advertisement,5)
   same => n,Dial(SIP/Roland_Test,,A(st-test))
   same => n,Wait(2)
   same => n,Hangup()

So i'd just like it to play this announcement once, and then continue 
with the normal ringing.

RetryDial also loops the announcement.

Only thing I can think of now is to record the announcement, and add 
some riging audio effects in the audio file, and just repeat that sound 
for a while.

Any other options? Seems like a common request to me :-)

Thanks in advance!
