A new phrase: open sip relay

The most abuse nowadays are open SIP servers, just as the old open mail servers which spammers relayed spam through. So we will use the phrase open sip relay about the scanning going on nowadays. Nothing new, just another protocol (but with much more money in than spam when you find one… )

Open SIP Relay by my definition is: a SIP server open to send SIP messages from whoever to whoever (even channel it through the PSTN network)
