Is there a way to blacklist an entire NPANXX? I’m getting robocalls from basically an entire prefix, ie 510-555-XXXX. I saw a few different instructions to create an inbound route, with callerIDNumber of - well a few different ways, check CID Priority, and destination terminate, but nothing works. Thanks

Hi!
Apparently if you create a different inbound route (with a different destination) to do that you must precede the pattern with a “_”… I have never done it however so I can’t say…
For one area code it sounds to me like the preferable solution if you can get it working…
The other two ways I could see to do that would be
- Custom code
- Bulk loading/importing into the blacklist (using a .CSV)… I don’t think that would be such a great idea since you would have to find a way to generate those 10000 numbers and apparently that database is ill suited to have too many entries…
Good luck and have a nice day!

Hi,
Thanks for the reply… I think I tried
_510555.
_510555XXXX.
and without the period for the Caller ID Number. And CID Priority, and destination terminate call… 
Assuming the calls are not coming in as 1510…
_510555.
_510555XXXX(no period)
should work.
Did you look at your logs?
The Caller ID - per the CDR reports:
+15105551212
I think I tried with the 1 too, let me try again…
Then if you are not stripping the + in the trunk your inbound route should be
_+1510555.
_+1510555XXXX

Oh Genuis! Thank you! Yes, I don’t strip the +1… so just ‘assumed’ when people said “use _510” that would work So I just tried calling from my work, different area code and prefix, but it works! So do I need both +1510555. and +1510555XXXX or are they both the ‘same’?
Thanks again!
Use one or the other. Not both.
Are they the ‘same’ or is there a reason to use one vs the other?
They are not the same but in your case it should not make a difference.
+1510555XXXX will match only 11 digit numbers
+1510555. will match any number that starts with that sequence
