Kamailio supports port reuse. You just need to enable this feature in the config file and then start several Kamailio copies. For example using different systemd units.
If I am not wrong, Kamailio supports distributing load to different processes forks on different cores. This is a present out of box and you do not need to do anything more. Just need to create additional UDP childrens.
