I use ChanSpy for that.
This should get you on track:

I don't use AMI, I just trigger asterisk binary through a shell script
(via AGI) like this to originate the call, it's easier for me:
/usr/sbin/asterisk -rx "originate local/something@whisper extension
something@whisper-playback"
[whisper]
exten => _[a-z,0-9].,1,Answer
exten => _[a-z,0-9].,n,Verbose(... whispering to admins)
exten => _[a-z,0-9].,n,ChanSpy(SIP/${EXTEN},qw)
exten => _[a-z,0-9].,n,Hangup
[whisper-playback]
exten => 5555,1,Answer
exten => 5555,n,Verbose(... playback to chanspy for admins)
exten => 5555,n,Playback(/var/lib/asterisk/sounds/somewavfile)
So, if you need this periodically you could maybe spawn a shell script
through AGI which will sleep for a certain amount of minutes and then
repeat the originate command ...
Good luck!

Hi.
I am using an appliance as SIP-ISDN gateway that has a (not so nice)
feature of hanging up a call if it detects more than 10 minutes of
silence from the originating side.
The problem is that the calls are always originated from a digital
system that, most of the times, just sends silence, for more than 10
minutes, only sporadically has people talking, so this makes the calls
to hangup automatically after 10 minutes...
I need to inject some noise/tone, periodically (like every 9 minutes),
on the originating call to avoid this behaviour. What is the best way to
achieve it?
I've seen the Extenspy or mixmonitor commands, but i need to make it
periodic...
Thank you in advance.
Rui
