I don't have a problem I need to know how to block calls that come up unknown caller without a telephone number. I tried *69 but got a recording that it was out of my area.
Star 69 is Return Call, and will recite the last number to call you, but will not work with office phone systems, or outgoing trunked lines. A good rule of thumb about *69 is its works on nearly all residential lines, and nearly no commercial lines. No phone can stop blocked ID calls but your dial tone provider can. Its called Call Block, and it will intercept anyone who calls you with *67 Caller ID Block, or anyone who tries to conceal the Caller ID pulse from their outgoing call to you. They are routed to a message that says "The subscriber you ar trying to reach does not accept blocked calls." Most carriers do not charge for this service, but you do have to ask for it.
As far as unknown callers, even with Call Block, as long as the caller does not actively conceal their number, the call will go through, even if your carrier cannot ID the number. Unknown is exactly that. Someone calling you who uses a different carrier than you, or a different type of dial tone than what you have might show up as an unknown number. Many people still use landlines from Verizon, but many have switched to Internet based-carriers who use a small piece of their internet bandwidth to create a virtual dial tone. This is called VOIP, or Voice Over Internet Protocol. These carriers have to " add-on" the Caller ID info, and not all carriers recognize each other's " add-on" information.
Believe me, I agree with you. The phone is for MY convieience, not for anybody else's. When called, I consider it an invasion of my privacy, and will answer only if I decide to. I most certainly DO NOT feel obligated to answer ANY phone of mine, and do so only at MY convienience. If there was a way to stop incoming calls that are simply unknown, or out of area, I would've found out about it.
I've been a telecom technician for 19 years, and I've yet to see a landline phoneset that could block user specified types of calls. Any sort of call blocking is done at the carrier's local Central Office that you are connected to. Any standard dial tone in your home originates at the carrier's C.O near your home. Its where all the phone lines in your community, the lines on your street, whether above ground on poles, or buried underground, all come together in one building. There are many C.O.s across the country, about one every 5 or 10 square miles, but every individual residence is connected to only one.
Here at the C.O., sometimes called a " switch, " is where your dial tone is generated, and cross connected in the array to the cable pair assigned to you that goes to the terminal nearest your home. Also, any special features you've ordered are added to your line here. This is also where youtr incoming calls get routed to, no matter where in the world where your caller is. This is where the digital switch routing of your incoming call ends, and where your physical copper line circuit begins.
Once the call passes THRU the switch, out goes the ring pulse on your copper phone line circuit. Out the building, down the road it goes, that copper cable pair can be up to 25,000 feet long. That's about 5 miles. Somewhere near your home is a telco terminal where your individual house's telco drop line connects your house's jack wiring terminal ( sometimes called a NID, or Network Interface Device) to the outside terminal, which houses a number of telco cable pairs, to supply all the residences within reach of that terminal with service.
Once a caller's ring pulse goes out of the local switch, the phoneset at the end of the circuit is going to ring, whether we want it to or not. We could turn off the ringer, but then we wouldn't know about any calls. So most carriers WILL stop deliberately blocked calls, but with the absence of that, there are too many reasons for a number to be simply not identified for the phone company to block them all. Good Luck!!
