I'd really need the complete numbers and run them through my system, but the first number you give doesn't exist (at all, it's not a valid number anywhere in the world), the second is probably from the same place as came together.
Therefore you are recording masked numbers, used by telemarketers to stop phones rejecting them with withheld numbers. Most are things like 00000 etc or 011234 and the like, but can use whatever rubbish they like. Take no notice, they are all calling from outside the UK and totally outside British law and unless you answer one of the recorded messages and press the button they ask you to can't do a thing.
