I have a panasonic, you have to look thru manual, but the commands for mine are menu #217, can block up to 30 numbers and menu #240 blocks all calls that do not display a phone number.
woke me up, holiday (VJ day) some BS about senior citizens. Told them wrong number they want my son lol. You think they can figure out if my son is a senior citizen I must be pretty damn old.
At least one call per day. Listed as "private caller" on caller id, so I do not answer. As soon as answering machine message kicks on, they disconnect the call. I have tried asking that my name be removed from calling list for numerous calls of this type and when I do, they don't respond and disconnect the call in the middle of me asking to remove my name from their calling list. Doesn't do any good to report to Do Not Call; they don't respond either!!
