That would require that the true CNID of the originator were not supressed. Does BT automaticalkly block calls with mising true CNID?
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.
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.
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?
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.
Are you sure?
I thought there was a BT Blacklist of spammers that were automatically blocked, correct?
