Does anybody know in which situation the NONCE_REUSED return code for www_authenticate would appear? I understand the usage of the STALE_NONCE code, this is when the nonce expires and the servers sends a new nonce to the phone. But why is the NONCE_REUSED used and why does it occur sometimes? Should I reject or accept the registration when this code appears?

NONCE_REUSED        /* Returned if nonce is used more than once */

Hi Catalina,

this is related to a security enhancement that was added about half a year or so. Take a look at the announcement of this functionality for more informations: http://lists.kamailio.org/pipermail/users/2008-June/017696.html
