Asterisk, Goto+Hungup - asterisk

Question

There is an extension, for which I need a random sound file to be played, and once it's played the call should be hung up. I have the below dialplan which plays, for example, the 2nd playback and then 3rd one is played etc., but it should hangup after playing back one sound file
exten => 123.,7,Goto(${RAND(8,12)})
exten => 123.,8,Playback(/var/lib/asterisk/sounds/customer_Menu1)
exten => 123.,9,Playback(/var/lib/asterisk/sounds/customer_Menu2)
exten => 123.,10,Playback(/var/lib/asterisk/sounds/customer_Menu3); after playback it supposed rejected..
exten => 123.,11,Playback(/var/lib/asterisk/sounds/customer_Menu4)
exten => 123.,12,Playback(/var/lib/asterisk/sounds/customer_Menu5)
exten => 123.,13,Hangup()
exten => 123.,14,Hangup(34)
How can I make this work; calling, playing only one random menu and hanging up?

Answer 1

Just give the hangup command a priority label and add a Goto() pointing to it after playing each item.
Also:
if you want to use pattern matching for an extension (I assume that's why you have a dot after 123) you should prefix it with an underscore
same can be used in place of exten => ... for the extension when you're repeating the same thing
n can be used for the next priority so you don't have to worry about keeping all the numbers straight
Now if we get rid of the priority numbers, what do you use in place of Goto(${RAND(8,12)})? More labels:
[mycontext]
exten => _123.,1,NoOp("start of context")
; ...
same => n,Goto(menu${RAND(1,5)})
same => n(menu1),Playback(/var/lib/asterisk/sounds/customer_Menu1)
same => n,Goto(goodbye)
same => n(menu2),Playback(/var/lib/asterisk/sounds/customer_Menu2)
same => n,Goto(goodbye)
same => n(menu3),Playback(/var/lib/asterisk/sounds/customer_Menu3)
same => n,Goto(goodbye)
same => n(menu4),Playback(/var/lib/asterisk/sounds/customer_Menu4)
same => n,Goto(goodbye)
same => n(menu5),Playback(/var/lib/asterisk/sounds/customer_Menu5)
same => n(goodbye),Hangup(34)
Or, more simply, use the RAND() function to choose the name of the file to play:
[mycontext]
exten => _123.,1,NoOp("start of context")
; ...
same => n,Playback(/var/lib/asterisk/sounds/customer_Menu${RAND(1,5)})
same => n,Hangup(34)

Answer 2

Should be something like this:
exten => _123.,7,Set(FILES=customer_Menu1:customer_Menu2:customer_Menu3)
same => n,Playback(${CUT(FILES,:,${RANDOM(1,3)}); CUT will get nth argument delimited by :
same => n,Hangup(34)
Or like miken32 show you if your files are always same name.
Also nice idea is move configure variables like FILES in [general] section or special file included in code.
You DO NOT need /var/lib/asterisk/sounds/ before every file. Just check that in your /etc/asterisk/asterisk.conf sound path is /var/lib/asterisk/sounds(default).
