Hello, there was a regex check on uri and aor, requiring a dot (.) in the domain part. Obviously that fails for IPv6. I pushed a commit to relax that check: - https://github.com/kamailio/kamailio/commit/94e9d47d2d2da82be23f1bae8cd6491… Now it is in master, it will be backported to stable branches soon.
