Can't Block 1-805-580-5224

Can't Block 1-805-580-5224

Hello all,

 

This number,1-805-580-5224, cannot be blocked because the Caller ID information is being delivered with a prefix of 1 (in front of the 10 digit number). This can only happen when the originating equipment has a direct connection to the SS7 signaling network because the normal SS7 signaling does not deliver any dialed prefixes. In essence, they are originating the (false) Caller ID information and the SS7 network is just passing it along. They must have an optical remote PBX or something similar to be able to send out their own (false) Caller ID information.

 

I tried adding the 10 digit number (without the 1 prefix) and it did not block the next incoming call. I also tried *60 then #01# after the last call and it said the number was already on my list. So, my only recourse was to answer the next call, listen to their introduction before interrupting, and then firmly asking to be removed from their list. They said they would remove my number and I haven't received any additional calls over the past 3 days.

 

FYI, this 1-805-580-5224 is trying to sell alternative energy provider services. I didn't catch their name but I would avoid them like the plague!

Thanks for the followup information UHFind,

 

I'm hoping I'm OK until my state and federal Do not Call Requests kick in and, hopefully, they'll abide by my new do not call listing. However, if they persist, I'll look into it further per your advisement.
