FYI, they are generated by a python suite called SIPVicious (ha ha nice pun)(http://code.google.com/p/sipvicious/) . More on this http://blog.sipvicious.org/. The suite was developed (really really extended the sense of the word "developed" here - as the scripts are really basic) by a security company who trails over Europe giving lectures on Voip security. :)

SIP Vicious does have a kill command... I've tried launching that on detection with mixed results. Triggering it from a hash count might prove better.
