Hi, excuse me if this message is not directly related to Kamailio.
such debates are welcome all the time.
I'm just wondering if folks could share with me if (and how) they have prevented the "SIP Digest Access Authentication RELAY" in their networks (and what worked for them or not).
To be sure we talk about the same thing, is this the issue described at: http://madynes.loria.fr/TeamMembers/Abdelnur/madynes-security-advisory-sip-d...

NAT boxes reduce dramatically the scenarios for a successful attack. Otherwise, some might be mitigating the attack by means of forcing UAs to use outbound proxies while others might be reducing the attack incentives by means of message integrity.
Any comment would be appreciated,
