[Asterisk-Users] pre-paid (new to asterisk, pls don't shoot on me)

[Joe Hughes]

On this subject - has anybody managed to implement a method
of warning the caller that their call will expire? I've
written a similar PrePaid test app in PHP/mySQL, I can
calculate the timeout for the call and set the timeout etc -
but I'd like to warn the user with beeps 15seconds before
the call is disconnected.

I've tried modifying the source so a flag is set "whentowarn
= (whentohangup - 15 seconds)", this gives me the ability to
execute a line in the main call loop.  If I execute
"ast_streamfile c, beep, c->language" the call bombs out. (I
don't have the error to hand)

Two questions; 

Has anybody successfully implemented this, either by way of
source changes or by using the T extension (possibly
something obvious I've missed?)

Is it possible to interrupt a call with ast_streamfile, if
so what is the correct sequence of code to do this
(waitstream, stopstream etc?)
