Re: [Homephone] call id spoofing and contact phishing?

I don't buy the fact that Bell (or any phone company) can't do anything about spoofed caller ID.

For example, they know perfectly well how to bill for calls made to toll-free (1-800) numbers, regardless how hard the caller might try to spoof their number.

We have a toll-free number at $dayjob, and I look at the billing statement for that line and I see the actual phone numbers that call us.

It's high time that if you pay extra for caller ID (and ESPECIALLY if you pay 75-cents and hit *69) you should da mn well get the actual phone number calling you - bypassing what-ever garbage is being forged by the caller.

Bell knows the actual ID, but there are legit business requirements to override that.

1) small company, say 5-10 POTS. PBX will outbound from any available line. They want a single caller ID to be used for consistency.

2) Larger company with a central VoIP PBX and remote locations. They may want a local caller ID to be sent when a branch makes a call.

It's not as simple a solution as you think.

There are two numbers carried with the setup information for every call - the Caller ID information and the ANI information. The former is used for display purposes, the latter for billing. They don't always match. There are legitimate reasons to change the Caller ID information. There are also ways to screen the customer supplied Caller ID information before the LEC passes it along. Sadly, that's often not done.

Anyone who paid 50 cents or a dollar (or what-ever the current cost is) for a *69 report and got that billed on their phone bill should have the ANI information show up on their phone-bill as a line-item piece of information for that instance. No excuse for not doing that. It would be no different than what is seen on a toll-free call report.

I dare anyone to explain procedurally or technically why Bell or any phone company couldn't do that. If they're billing you for the information, you should danm well get the information.

And while we're on the subject - are you still charged for a *69 when the info comes back as "We're sorry - the last number that called you is not known." ??? That would never happen if they gave you the ANI number.

CRTC Privacy Regulations specifically prohibit disclosure of the ANI. In the case of tollfree calls, the recipient is paying for the call, so they're entitled to know the source. Personally, I think even that is a bit sketchy.

Got to remember the calling party / calling party telco is responsible for the caller ID and ANI ifo. The receiving party / telco has only the info provided by the calling party / calling party telco has no way to validate the info it is provided.

Billing is largely done through the calling party's telco.

For tollfree calls, the billing is done by the called party's tollfree provider.

with tollfree calls, all that matters is the region the call came from and duration to allow Receiving telco to bill. They dont have to know individual calling party subscriber info.

with added services calls 900 service, the calling party only need be identified up to the called party telco. The called party doesnt need ID. all they know is that their telco has billed the calling party's telco at the prescribed rate and remitted the money to them. It doesn't matter who it actually came from.
