asterisk users - Sep 2009 - play audio file within an active call

Hi,

I'm wondering if someone can share their thoughts on how to implement a
system that periodically checks active channels which have been up for more than
X minutes and plays/injects a sound file. The idea is to simply warn users that
they've been on the phone for quite a while and maybe they should consider
hanging up. If the call stays up for more than Y minutes, it is dropped
automatically (softhangup).

What's the simplest approach to playing a sound file within an active
channel?

I thought of writing a cron agi script that scans active channels, retrieves
their duration and if it's > X minutes then "RedirectChannel"
to a context which executes a Playback(file); if it's > Y minutes then
"RedirectChannel" to a context which executes both a
Playback("forcing hang up now...") and HangUp.

Any thoughts?

If you redirect the channel, the person they're talking to is likely
to be dropped.

The only way I know of doing this is with a conference bridge like
meetme. You would have to have both parties in the conference and then
call the 3rd party (your msg) into it.

I think you should be able to do this with ChanSpy and the whisper
option. However, Asterisk already has a facility for this. This is from
core show application Dial

    L(x[:y][:z]) - Limit the call to 'x' ms. Play a warning when
'y' ms are
           left. Repeat the warning every 'z' ms. The following special
           variables can be used with this option:
           * LIMIT_PLAYAUDIO_CALLER   yes|no (default yes)
                                      Play sounds to the caller.
           * LIMIT_PLAYAUDIO_CALLEE   yes|no
                                      Play sounds to the callee.
           * LIMIT_TIMEOUT_FILE       File to play when time is up.
           * LIMIT_CONNECT_FILE       File to play when call begins.
           * LIMIT_WARNING_FILE       File to play as warning if 'y' is
defined.
                                      The default is to say the time remaining.
