Now, I am trying to modify the User-Agent header of OPTIONS sent by Dispatcher Module, how is this possible? I tried something like this, because insert_hf or remove_hf does not work in event_route: # Branch cleanup branch_route[MANAGE_CLEANUP] { remove_hf("User-Agent"); insert_hf("User-Agent: Test\r\n"); return; } # topos route event_route[topos:msg-sending] { # Topology hiding for some hosts if (is_request() and $sndto(ip)=="1.1.1.1") { if (is_method("OPTIONS")) { t_on_branch("MANAGE_CLEANUP"); t_relay(); } } else { # No topology hiding for other hosts... drop; } } But the branch-route is never called. I got two errors in Log: Apr 4 12:17:27 kamailio /usr/sbin/kamailio[32174]: CRITICAL: <core> [core/ip_addr.c:234]: ip_addr2sbuf(): unknown address family 0 Apr 4 12:17:27 kamailio /usr/sbin/kamailio[32174]: ERROR: tm [t_fwd.c:1752]: t_forward_nonack(): no branches for forwarding Any hints how to achieve this?
