Re: BT Call Protect

That would require that the true CNID of the originator were not supressed.  Does BT automaticalkly block calls with mising true CNID?

Re: BT Call Protect

Doubtful, as that would presumably block many genuine international calls.

Re: BT Call Protect

an interesting document indeed.

 

It says that for VOIP telephony (which this junk almost certainly always is) the switching data will just gve the IP address at which the call entered the POTS. If that could be used to block a call, which is somewhat doubtful, then it also could be spoofed.

Re: BT Call Protect

Does anyone know how to set up Call Protect without going online? My 80 year old parents would benefit from this as they are plagued by calls, but they are not online so would need an alternative route.

Re: BT Call Protect

You should be able to do if for them, with their permission, by using the online order page.

Re: BT Call Protect

Clarification please.

If I have Call Protect installed & I get a phone call where the number is withheld does this automatically get added to the BT blocked data base or do I have to add it to my blocked data base if so required?

Re: BT Call Protect

nothing gets added automatically. You have to manually tell them to add it to your personal blacklist.

"Number unavailable" calls can't be added. Withheld ones can.

The whole thing sounds about as much use as an ashtray on a motorbike.

Are you sure?

I thought there was a BT Blacklist of spammers that were automatically blocked, correct?
