Hello,

I created a new application for myself called Dialtone() by modifing
res/res_indications.c file.  It can be used as such:

    exten => s,4,Dialtone(30|${CALLERIDNUM})
    exten => s,5,Playback(time-exceeded)
    exten => s,6,Goto(s|1)

It will stutter if you have new voicemail and you have passed the mailbox
number as I did above.  It will stop dialtone the moment you press a key or
the timeout (in seconds) has occured.

This is my first stab at asterisk so I am not 100% that this is where the
code should live.  If there is someone out there that wants to add it to (*)
then please feel free.  I can send you the whole file if you need.

I needed this application because I need to set immediate=yes so that I can
set some variables when the phone is picked up.

Thanks,
Jason
