I'm using Kamailio version 5.3.7 with DISPATCHER module and I would like to integrate my kamailio with a kamailio_exporter for monitoring using Prometheus server.

Is it possible to collect data such as the number of total calls (inbound, outbound) and plot time-graphs using those stats?

If so, what modules/functions would I need apart from the Dispatcher module to be able to have efficient results?

Any degree of help will be appreciated.
