I could track that limitation down to commit c6b62bf8 from 2011. Searching on the web, I found that is a little bit tricky with link local addresses, especially related to porting on Linux and *BSDes (e.g., https://danrl.com/blog/2016/struct-sockaddr-in6/).
Anyhow, your code has hardcoded interface name, I added a helper function that tries to get the scope by matching the ip address when walking over network interfaces. The commit: * https://github.com/kamailio/kamailio/commit/ce1138d2d8962296de2867d5751abf770b035da3 Can you try using that function to get the scope id? Then, if works, we can consider adding some parameter to control if link local ipv6 addresses should be also bound automatically, so current behaviour is preserved.
