I've done this with RabbitMQ. I don't send any messages until the 180 ringing
comes through (and then in dialog:start and dialog:end), but there's no reason why you
couldn't do it on the initial INVITE.
Although the advice you received to do it asynchronously is absolutely spot-on, I
currently don't in one of my clusters, and it works fine inline. AMQP is quick, and
the server will acknowledge the message as soon as it is received from Kamailio, whether
or not it has been processed on the remote end, so there isn't much delay added.
You do of course want to make sure the AMQP server is available if you aren't taking
advantage of async processing.
I use a 3 node RabbitMQ cluster for high availability, and it is actually on a different
continent than one of my Kamailio proxies. That of course does add some additional
latency, but it still works fine.
I should change it to asynchronous though.

Subject: [SR-Users] Call History
Hello,
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!
