I have recorded a sound effect, use a callfile to play the file via the 
sound card.  I have a very short timeout for that extension.  I just 
jump back to the beginning on the context, play the sound effect and 
then ring the phone again.  Code below:


;******************************************************
;* If Press extension is dialed after 5pm, play bull
;* Horn sound effect to get pressman's attention
;******************************************************

[night_bell]

exten => 4173,1,GotoIfTime(07:45-16:59|mon-fri|*|*?press-officehours,s,1)
exten => 4173,2,System(/bin/cp /usr/local/bin/bullhorn.call 
/var/spool/asterisk/outgoing/bullhorn`date +%s`.call)
exten => 4173,3,Dial(SIP/4173,15,tTkK)
exten => 4173,4,Goto(night_bell,4173,1)


<bullhorn.call>

Channel: Console/dsp
MaxRetries: 0
Application: playback
Data: /var/lib/asterisk/sounds/local/bullhorn
