Re: Blocking Caller ID ? Many phone companies have a provision for public safety personnel to have your Caller ID information blocked permanently for no charge.

If you call a toll-free number, 911, or most numbers at law enforcement agencies, your number is always provided to the recipient. It doesn't matter if you block your caller ID or not.
Also, the suggestion that often comes up in the Spam Buster forum here to "call [a toll-free number you don't recognize] from a pay phone" won't always work. Many businesses block calls to their toll-free numbers from pay stations; some are even programmed to not accept calls from numbers they have not called. |

A prepaid calling card, like the ones you use to call long distance, leave the caller ID of the PPCC company on the caller ID of the person you are calling. It's usually a legit number like 301-322-9514.
They're cheap per minute so there isn't much of an investment.

Yup, and it's a little wider than that, even: businesses with digital service (ISDN BRI, PRI, T1, T3, etc. services) often receive ANI (Automated Number Identification) data for calls to those lines. This is not the same as CLID (Calling Line Identification)...as ANI cannot be blocked.

1 edit | Just to beat this topic to death. Any entity with a "digital trunk" connection to the PSTN receives both caller and destination information. Otherwise call could not be delivered. It is up the termination entity to decide how to handle it.
When you suppress Caller ID either on a per call basis or permanently a message gets sent to the terminating equipment requesting it to not generate Caller ID info as part of called party signalling. Caller ID information is sent to the called party using Bell 202 half duplex modem protocol. Caller ID info is transmitted during ringing and if you have Call Waiting as part of the call waiting alert.

Interesting since they don't know who the "real" caller is I assume this means the FCC requires they present the line number of the calling party. If call is placed behind a PBX they have no way to determine the extension so I assume they just report the Company's main #.

Two Caller-ID tidbits:
1) Calling a toll-free number (800, 877, etc.) is not caller-ID (it's ANI), and you can't block that delivery.
2) If you get always-block on your phone for outgoing calls, but you use speed dial for family and friends, add the unblock-code (*68?) to the start of the dial string so they know you're calling on their caller-ID box.

Why do You need to block your number? If you are calling someone with whom you socialize, why are you hiding your identity? Hum! makes one wonder what you have to hide. |

TracFone shows callerID in Ohio. Also they do ask you who you are when you activate the phone. And Boost is just Nextel still shows up the number unless you have it blocked. But untraceable. naaaaa. not much of anything is. |

AT&T Ohio says that no matter what a business is using for their telephone lines from them they provide your caller id information to them. even if they're using a standard phone line. So yah businesses always get it in Ohio that have service with AT&T |

said by whocares0:said by CipherDias:On a regular landline telephone is there any way to completely block the person at the other end from seeing the number you are calling from? yes but don't forget, some pple, (like me) have our landlines set up,so that no number/no name show, no calls accepted, I would like to do that but then I would miss important calls. Many business like hospitals have their service provided over a carrier system and the calling number is not generated to caller ID. |
