Hi, Over the past three days I have received two calls from the following numbers to my ex dir landline. 05818917617 and 04991882197. When the number calls me it is a strange continuous warbling sound (as though in an echo chamber) when picking up the handset on my phone the line goes dead. Enquiries to who called me from ...? have not drawn any conclusions or results. Is there anybody with any like experience of these type of calls or these two particular numbers.
Solved! Go to Solution.
The numbers will be spoofed by the scammers and will be meaningless. Ex-directory is irrelevant, the scammers don't look numbers up in a phone book, they dial thousands of numbers sequentially.
did you retain your number or get new number from BT these calls are just computer generated running through series of numbers one after the other
if that was for me...and not the OP...then i retained the number we previously had.
Was a BT number, it moved to NowTV...now back with BT but it is digital voice now.
numbers are like this: all within
past couple of days.
my DV allows me to block calls as part of DV by going to MYBT
