Hi , I have been getting phone calls from these numbers saying they are virgin media sale .. 08001836408 08001836411 08001836416 , I tried to contact virgin on the 150 number , got through to someone to talk about it then they cut me off after waiting 35 mins on hold .. Anyone know the answer
The caller ID is only part of the screening process. It doesn't matter if the caller ID is faked or not.
Known/approved callers logged in the phone/device address book ring straight through. Anyone else is challenged to state who they are and press a key on the phone. Only then does the customer's phone ring and they hear the announcement from the caller and can accept/reject the call. Any caller not completing the screening process has their call dropped without the customer's phone ringing.
Greatest benefit is against the automated diallers which cannot comply with the button press and so those calls are dropped without the phone ringing. Either of the devices mentioned restores the phone to normal use without having to manually screen calls and decide whether to answer or not. Even if a scam caller breaks through the first layer of screening, the recipient can still reject the call without speaking to the scam caller.
Just a matter of how many scam calls you receive each day and how much they annoy you as to whether the devices are VFM or not.
I run an older version of the BT phone provided above.
I have got 0 spam calls over the past 3 years.
The phone does not not make a sound unless your in my address book. Ive had no "spoof" callers. bare in mind they have got to know which numbers are stored in my address book to get through which is no way possible.
