Hello! Thanks to @cezar91 we finally spot the issue, basically kamailio it's transforming t_code=0 (timeout) to 408 and the dispatcher module sees this last value.
Oct 28 14:16:32 net21-test /usr/sbin/kamailio[31911]: DEBUG: tm [t_reply.c:1311]: t_should_relay_response(): ->>>>>>>>> T_code=0, new_code=408 Oct 28 14:16:32 net21-test /usr/sbin/kamailio[31911]: DEBUG: tm [t_reply.c:2135]: local_reply(): DEBUG: local transaction completed 408/0 (totag retr: 0/1024) Oct 28 14:16:32 net21-test /usr/sbin/kamailio[31911]: DEBUG: dispatcher [dispatch.c:2489]: ds_options_callback(): OPTIONS-Request was finished with code 408 (to sip:media21-test.internal:5060, group 3) So if you set on "ds_ping_reply_codes" class=4 or code=408, kamailio will consider the backend up even if it doesn't actually receives that specific code. Do you think it worth to update the docs and advice about this behaviour? I just spot now the typo on the first email about the code sorry!
