At this moment, if using jansson/json modules feels complicated, then try to leverage inline execution of a JavaScript snippet via app_jsdt (which has no external library). The JSON can be parsed into a JS structure, making it easy to access the fields. I use this mechanism every time I need to do complex operations with json documents.
An unrelated example, which can help getting started, was posted in another discussion a while ago: * https://lists.kamailio.org/pipermail/sr-users/2021-March/112156.html Of course, having the attributes accessible via native cfg variables would be good, but from my point of view it doesn't look like having any spare time anytime soon. Obviously, contributions are welcome! Cheers, Daniel On 06.07.21 16:21, Ben Kaufman wrote: > > As a convenience fact, having all the common values from the header > and payload would be nice.
