This advice is horribly. Just forwarding the request means that the proxy is an open relay, like open SMTP relays [1], and opens the door for SPIT and various other kinds of attacks. Of course forwarding will be done if the proxy belongs somehow to the domain (e.g. an outbound proxy should forward requests to the registrar - but only for the domains it belongs to) regards klaus [1] http://en.wikipedia.org/wiki/Open_mail_relay _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
