Got one today claiming to be VM. Claiming a problem with hub connecting to network or it's dropping signal. They are using the EVENTVWR script (see all the warning error messages) to try explain the fault and claim hackers are the problem.
I've just been moved to fiberphone due to a copper line fault (better known as VM Bull....)
Just letting people know in case they get one and check the forum.
Oh, I'll just leave this quote here.
"The hub based lines will be replacing ALL current PSTN landlines by 2025, as the old telephone exchanges are now life expired & no longer fit for purpose. A symptom of this is the plethora of scam calls that are now being made on a daily basis, none of which can be stopped by PSTN technology."
