I'd like to start tracking a call history/log as soon as I receive a call. I'd like the customer to be able to see that there's an incoming call to one of their numbers in real time.

I'm thinking of using the RABBITMQ Module to manually emit an event from my main route when I receive an INVITE. Is that a bad idea? What if the broker isn't located on the same host (latency/availability)? I don't want to negatively affect the call processing. 

I was looking at the Dialog Module and it has three event routes:
* event_route[dialog:start]

* event_route[dialog:end]

* event_route[dialog:failed]

It's really close to what I want, but I'd like to capture the dialog before it starts (Unconfirmed or Early). Maybe another option is to scan the Dialog table with an external process and emit events from there.

Has anyone had success in creating a realtime call history? Is there a better way to go about doing so?

Thanks!
