[asterisk-users] Callback/ringback

[Richard Soderblom]

Hi.

Has anyone had any success in implementing a callback or ringback
function in Asterisk?

I've had a look at the callback-voicemail example on voip-info.org
http://www.voip-info.org/wiki/view/Asterisk+tips+callback
However it won't quite work for me.

I need it for local SIP users which most of them don't have voicemail.
If one SIP user calls another SIP user and the second user is busy or
unavailable then Asterisk should inform the first user that the number
they dialed is busy and hangup the call.

Once the second caller is available again then Asterisk should initiate
a call back to both the users and connect them.

Any ideas on how to achieve this will be appreciated.

Thanks,
Richard
