How to block 4 digit call 1101, 1000, 1001 ... etc?

[DFSC]

Hi everyone,

I have obi 110, but i didn't have any landline.

rececntly i keep getting lot of 4 digit call! last nite i think i got about 20 call from 1101!!

I check GV, there are no record of those call in call history, so i cannot filter it!

What can i do?

Thanks everyone for help!

I'll bet your seeing a SIP Scanner.  Is your OBI 110 in a DMZ or in front of your router?

[DFSC]

no, its behind a netgear r7000 router, i dont think i have setup dmz on that router. I just use default setup of that router!

any advice ?

You shouldn't be getting these calls with GoogleVoice. I assume you have GV defined on SP1. Do you have another service defined on SP2?

thanks i think i previously setup callcentric on sp2 and that those annoying call coming from, now i just disable sp2 see if i still get any of these crap, thanks!!! again

Also, did you map port 5060 to your obi in the router?  If so, remove the mapping.
