Maybe you should introduce yourself into the basics os SIP, e.g by reading 
http://iptel.org/ser/sipintro.html. There is a header field called 
Max-Forwards which prevents endless loops (or cyclic attacks how you call 
it). And naturally SER can check this header filed if you do it in your 
config script.
