Re: [asterisk-users] Callback/ringback
Richard Soderblom wrote: 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. Richard, That shouldn't be too difficult to do. I recently wrote an agi binary that does nag calling for me which I think is related to what you want to do except that I am doing more calling out of the system. Maybe deadagi could work? Here is it's use in a AEL macro I'm working on: http://www.datatrakpos.com/pos/datatalk/images/nagcall.htm The AGI (nagcall) simply takes some parameters and uses them to create a .call file. See: http://www.voip-info.org/tiki-index.php?page=Asterisk+auto-dial+out There is even an example on the page above that shows using the linux "touch" command to schedule the call to take place at a later time, although I have not successfully done this yet...still trying. The biggest difference is that you will need a way to monitor the called extension to trigger a call back to the original caller using maybe deadagi or .call files? http://www.voip-info.org/wiki/index.php?page=Asterisk+manager+API I'm pretty new to asterisk myself so there may be (probably are) other ways to do this, but this is where I would start poking around. -- Warm Regards, Lee ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Enclosed bellow is the fragment from extenstions.conf which does two things:
*41 - Does the ring-back staff.
*42 - Calls back the last one who called you.
