Neither checking $rU? do you mean that checking $rU in branch_route is not valid in 3.0? > Any ideas on how to accomplish dropping a specific branch? If you use it to drop requests going to "unsafe" destinations (like when a REGISTER contains a spoofed "Contact" URI pointing to a gw or the proxy itself) then I recommend using blcklist for this purpose. This is, you set the list of IP's for gateways and proxies (forbidden addresses into a registration Contact) and enable such blacklist after doing lookup. If a branch tries to go to one of these addresses it will be dropped by t_relay (and will return certain code I don't remember now). I use it and works well. -- Iñaki Baz Castillo <i...@aliax.net> _______________________________________________ Kamailio (OpenSER) - Users mailing list Users@lists.kamailio.org http://lists.kamailio.org/cgi-bin/mailman/listinfo/users http://lists.openser-project.org/cgi-bin/mailman/listinfo/users
