I think this is it:
Panasonic 1000 Series DECT 6.0 4-Handset Expandable Telephone with Digital Answering System (KX-TG1064SK)
I recently bought it from BJs wholesale club. It has a landline phone on the base with an answering machine and 4 cordless phones. I checked my MILs phones- we bought her Panasonic phones about 4 years ago- and that phone also has this feature so it might be standard on Panasonics. It is WONDERFUL. When caller ID shows Satan’s spawns calling, I go through the prompts of saving their phone number and am given the option of saving it to ‘phonebook’ or ‘call block’. If they try to call me, the words ‘call blocked’ show up on my caller ID.
thanks
I bought some really nice Panasonic phones a few years ago, but they don’t have that feature. :(
