Hello, I'm trying to implement a function available on the PSTN net here, if
you dial a number which is busy and you press 5, you will be called back
when the busy party hangs up.
Figuring out if a SIP user is busy isn't to hard, ${DIALSTATUS} produces a
BUSY message, however, how can I implement the call back?
IE, I dial to extension 712, but that extension is busy, I dial 5 and
hangup. If extension 712 is no longer busy I'm called back and the moment I
pickup the extension 712 is dialed again.
I'm thinking something like putting a value in the Asterisk DB if the
extension is busy, after that extension hangs up it should trigger the dial
to the originating extension and on pickup it should dial the other
extension :-)
Kind regards,
E. Versaevel

Or in a ideal situation an application that notices peer changes and creates a trigger. (Manager API Events) Wait for Hangup, check Hangup->Channel in To5-DB if in call Callback context (extension script should handle pickup/call To5-DB/FromPeer) Greetings, Stefan de Konink

Look at the wiki for more information. Icd supports callback queue members. I.e. put them in a queue and if they press 5 you re-add them as a callback queue member. Peter
