They're traceable with some effort by the telcos but if the trace goes to some butthole place in India what are you going to do about it?
Maybe calls could be blocked by providers based on the SIP headers. If an abusive IP address is detected the call gets dropped. But it would be quite an undertaking to compile such a list, especially once the transition to IPv6 is complete. Also there's the problem of morphing IP addresses. I can easily pull a new public IP address by restarting my router, much like changing one's outgoing CLID.
It will likely be left to the end user to harden their own systems. Perhaps routers that drop connection attempts from blacklisted blocks of IP's programmed in CIDR Notation. Still a major PITA to ferret out the bad guys.
