Hello,

I have another question.


I've built libjansson from sources, and now I'm trying to find how to configure 
Kamailio to use it, but I'm not sure how...

I see it's using pkg-config, so I've tried to export like this:

export PKG_CONFIG_PATH=/.../jansson/2.14/lib/pkgconfig

The following commands do work:
pkg-config --libs jansson
pkg-config --cflags jansson

But then when I build Kamailio, I see the jansson module is in the 
"exclude_modules" list (in src/modules.lst).
Even though I've added "jansson" in the include_modules of command "make cfg".


Any idea ?

Regards,
Nicolas.

Ah, that looks easy indeed. Just have to build that module. :) Thanks!

I don’t think there is any practical RPC method restriction, but parsing the 
JSON body in script is indeed possible, easy and pretty cheap:
