I want to implement an automated IVR-like service that will be used for calling selected customers and performing a survey/collecting some data from them.

I decided to use mod_httapi for handling the calls, but since my application will be calling the customers I need to initiate the call too.

I'd like to do that using an inbound event socket, by sending 'originate' command.

And my questions are:

1. Is this a correct approach, or maybe there's a better method of initiating such call?

2. How to pass some correlation id when originating the call so that it would be delivered back to my application with mod_httapi request? I just need to correlate the initiation of the call with the call handler code that will be invoked later.

Thanks and best regards
