[SR-Users] Return value from lua/python/js/bash/etc... function

8 Feb 2023

What is the simplest way to return values from external application into 
Kamailio config and assign it to a variable?

I'm looking for the most light weight mechanism to do it and to offload 
some logic to external app. Something like this would be ideal:

$var(myVar), $var(err) = lua_run("lua_func1", "$rU");

OR

$var(encString) = exec_cmd("echo 'abc $rU' | base64");

There is this method:
http_client_query("http://...", "", "",
"$var(result)");
but there is an overhead of networking and HTTP protocol.

Please advise.

Thanks, Dmytro
