@miconda after [c309122](https://github.com/kamailio/kamailio/commit/c309122864eaa2bfa58253290bed4908...) it looks like everything is working as intended now. Thank you for the quick fix. As I mentioned before we have tested it by backporting the change on 5.5.4. We'll be testing these changes in the next days so we can avoid unexpected problems and we'll update this issue accordingly.
