I was very happy to see the news of the release of a new Kamailio module, authored by Victor Sveva.
CFGT can be used to test call scenarios and see what routing logic was triggered in Kamailio.
Test calls need to be marked with a specific, configurable Call-ID pattern ('callid_prefix').
A JSON report is generated, with the possibility to choose what variables to dump into it.
This is going to greatly simplify testing, while potentially keep the logging to a minimum. Highly recommended.
