I want to use ka_add_destination function of KA module but i am getting this error :
[root@SBC-4-1] kamailio -c -f /usr/local/etc/kamailio/kamailio.cfg
loading modules under config path: /usr/local/lib64/kamailio/modules/
 0(48016) ERROR: <core> [core/cfg.y:3451]: yyparse(): cfg. parser: failed to find command ka_add_destination (params 1)
 0(48016) CRITICAL: <core> [core/cfg.y:3592]: yyerror_at(): parse error in config file /usr/local/etc/kamailio/kamailio.cfg, line 1449, column 58: unknown command, missing loadmodule?

I know that 5.3.3 version does not support this function but 5.4.0 should as per documentation :
https://kamailio.org/docs/modules/5.4.x/modules/keepalive.html#keepalive.ka_add_destination

Keepalive module is compiled and loaded in cfg.
