[VoiceOps] Disclosing Restricted Caller ID to customer

[Matthew Crocker]

If they are an end-user the SIP INVITE should be sanitized by the providing carrier.

Carrier <-> Carrier include CallerID with privacy bits set
Carrier -> End-user include Sanitized CallerID (i.e. Anonymous or Private in the From header,  no Remote-Party-ID)

Cool,
Looks like it is similar laws here in the USA too..
I stand corrected…

https://www.federalregister.gov/documents/2017/12/01/2017-25917/calling-number-identification-service-caller-id

Though I am curious about a scenario…
Client is running his own pbx, and running Homer ..
Would the Caller ID be visible to them in the homer trace ?

Can’t speak for US, but at least in Canada what you described wont fly.

You have obligations as a carrier to honour restricted caller id received from PSTN if the caller choose to withhold it. If your paying customer is not happy with a private incoming call, they should contact police as someone earlier suggested. If deemed necessary, police or court or whatever authority will reach to you for the private caller id.

If you just disclose caller id on your customers request as you described, you may just as well disregard rpid / whatever privacy flag you have from pstn all together. But people dont do that afaik.

Your obligations are to your paying customer….. (which in this case is the Called Entity)
You have zero obligations to the caller….
If your client is asking for the information, and you have it, you may choose to provide it.
What your client does with it, is not your concern.
(Law enforcement overrides your agreement of keeping your clients information confidential )

My two cents !

You don’t know if it really is harassment.

Tell the customer you have the call details and will retain the data for 90 days.  Have them call the police and open a case for harassment.  The police can get a subpoena and request the call data.

Greetings all, Had an interesting case come up today that I wanted some feedback on.

Customer called claiming they had been receiving harassing calls to their business number, But the calls were caller ID blocked (Caller likely dialed *67 before the call). I found the CDR's for the call in question, And sure enough "Anonymous" <Restricted> was the displayed Calling number and CNAM.

Out of curiosity, I went and pulled the capture of the same call from Homer. And sure enough, The actual calling number is delivered in the Remote-Party-ID field, With Privacy=full.

Obviously, The caller asked for... and expected that data to be private. What's everyones thoughts on the legality of disclosing that information to my customer receiving the call? Would you provide it on request to the end user? Or limit that information only if requested by legal request? (Court order or request from law enforcement)
