SIP scanners on the internet are probably hitting the router which is happily passing traffic through because it knows the phone is using port (well, you're talking on it so here's some traffic for it!). What I've been doing is move the SIP self port for the phone to a different port. seems to solve the problem.


Ex-Norstar, ex-Definity, current NEC/Zultys/Hosted/sometime-IPOffice, wait, what? another damn system? kill me now.
