   One solution to SPIT is to require an IPsec SA (Security Association)
   before a correspondent user opens a session with a target SIP URI.
   If later the correspondent user turns bad and sends SPIT, the target
   user can remove the SA.

I don't understand.  So, I would send you an INVITE, and then you
would challange me by doing ... <what>?
