The problem is that source address family is different than target address family, and HEP seems to have only one field for address family: - https://github.com/kamailio/kamailio/blob/master/src/modules/siptrace/siptr… - https://github.com/kamailio/kamailio/blob/master/src/modules/siptrace/siptr… So apparently you need to extend HEP and Homer Sipcature server, not only siptrace. I am closing it as it looks not something easily to deal with, it is not only about Kamailio. If I am wrong, you can reopen, or just make a pull request with the changes. -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3665#issuecomment-1847508395 You are receiving this because you are subscribed to this thread.
