Hi. New here. It is 4:57am as I begin writing this... been up since 4am... sure you can figure out why
First, I'm unclear on a lot of all this but THANK YOU for the solution. I keyed in quickly that Oleg's method is preferred. I inputted that (while under attack), hit reboot... problem solved. So that's fine, except:
1) I don't understand WHY it works or WHAT it does, so I'm not all that confident that I didn't just block everyone from calling me.
2) I don't understand why my PROVIDER isn't solving this issue. I use Callcentric, which seems to me to be a large, reputable, and experienced provider. Why are they using default ports and allowing such attacks to their customers?
3) I'm also trying to figure out if the reason for these attacks suddenly hitting me is because a) I switched from voip.ms
to Callcentric or b) I switched from a PAP2T to a OBi100 or c) I switched from being behind a router to being in front of it.
Some more information on #3:
- I switched to Callcentric because they could port my home # and voip.ms
couldn't. I was happy at first because the call quality seemed immediately better. HOWEVER, I've been battling frequent problems of calls disconnecting @ 5 minutes and/or one-way audio (always on incoming calls).
- Due to those problems, Callcentric suggested the problem was with my PAP2T device, so I got an OBi100. The OBi was never used on voip.ms
. That's why I don't know which is causing this SIP attack issue (that I never had in YEARS with voip.ms/PAP2T).
- When switching to the OBi didn't help (dropped calls/one-way audio) they suggested it was probably my router, so I plugged it directly to the modem's 2nd port (mine has 2 available ports each getting its own WAN IP). That actually appeared to resolve the problem because immediately from the very first test call after that switch for the next 48 hours... not a single dropped call or one-way audio issue. However, after that (with no changes at all), back to frequent drops and one-way audio on incoming.
And, of course, now as of 4am... annoying bloody calls from these sip scanner attacks.
So now its 5:05am... still no calls since implementing the Oleg fix. I'm going back to bed for the next 45 minutes or so before my 2yr old wakes up (sigh). Hopefully in the morning you guys will have me comforted that Oleg's method isn't blocking wanted calls and maybe, just maybe, someone can give me some tips on my other problems (though I realize that's off topic)
