OBi + GV: Neighbor Spoofing Robocall Blocking

(1/3) > >>

slow_quick:
I found a way to block "Neighbor Spoofing Robocall" using OBi device + GV.

Hypothetically assuming:
1. my GV number is 402-346-1400 and this is my SP1;
2. I have 3 friends in the neigbor area, 402-346-1401, 402-346-1402 and 402-346-1403

I would like to block 402-346-xxxx except for 3 friends' numbers.

First I set up 2  user defined digitmaps:
wlist = ( (+1|1)? 402 346 (1401 | 1402 | 1403) )
blist = ( (+1|1)? 402 346 xxxx )

I then set up SP1's InboundCallRoute:
X_InboundCallRoute = {(Mwlist):ph},{(Mblist):sp1(14025551212; ui=$1)},{ph}

The first rule is white list, let friends phone to come to my phone.  The second rule is black list, all other neighbor phone numbers are captured here, and forwarded to the directory assistant number 402-555-1212.  Google Voice tells the caller "We can not complete your call.  Please try again.", click, disconnected.  If the incoming call does not match the first two rules, it passes to the last one, the phone.

My land-line phone (GV+OBi200) is so much quiter now.

This method is good if you've moved around and kept the old number so you have only a few old "neighbor" friends, making it easy to come up the white list.

Aha, I'm re-inventing the wheel.

Tried your way: {(Mblist):}, it works by simply ignoring the call, so my GV voice mail answers it.  Using my method: {(Mblist):sp1(14025551212)}, the GV picks up, tells the caller "can not complete the call" and hangs up.  Nothing left in my GV voice mail.

Thank you to the OP. I just set this up on my Obi202. I have been getting these fake "neighbor" robocalls for years. I have already blocked many in my dialer app on my mobile phone, but then they just get diverted to voice mail (blocking in the dialer app just suppresses the ring). I would rather have them dead-end. I also have been blocking these calls on-by-one in GV, but every time the last 4 digits change, a call gets through. I would love a way to do similar in GV for the robocalls that dial my mobile number directly, and then GV answers for voice mail. Thank you again.

Sheffield_Steve:
Do you have the "Global Spam Filtering" option enabled in GV?

I do and very rarely do I get a spam/spoofed call.
