[SR-Users] failure_route - no UAC support

Hello, I'm trying to restart phones with local-requests (from config or kamctl cisco_restart). I can enable t_on_failure("REMOTE_AUTH") in event_route[tm:local-request] but when 401 Reply comes in I get this warning: "tm [t_reply.c:968]: run_failure_handlers(): no UAC support (1, 0)". kamailio -V version: kamailio 5.1.8 (x86_64/linux) flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144 MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled with gcc 6.3.0 How can I make it work? Thank you! Regards, Attila
