How to Increase Maximum Concurrent Calls in PJSUA2 Beyond Default Limit (SOLVED)

Hello, does anyone know how I can make more than 4 simultaneous calls in PJSUA2?

I have added the following to the config_site.h:

*cpp:

#define PJSUA_MAX_CALLS                 400
#define PJSUA_MAX_ACC                   400
#define PJ_IOQUEUE_MAX_HANDLES          400
#define __FD_SETSIZE                    800
#define PJSUA_MAX_PLAYERS               400

Nevertheless, when I call pjsua_call_get_max_count(), it still returns the number “4”!

Edit: Solved, there was an error while “make”. Put back the original call.cpp file solved the problem.
