This is the first to get through the net, since I installed our BT
8500's with the TruCall system 8-o .

The system logged a series of calls from 01134196912. Which at first
glance suggested it might have been a genuine and local number, so I
tried ringing it back and it rang unanswered, though it did sound a bit
odd the ringing tone. The caller had failed to announce their name and
press # to get through in each of their calls.

Then I tried to trace where the call had originated 0113 is a Leeds
code, also our area code, except all of our codes (so far as I am
aware) have a 2 following the code - 0113 2??????. 01134 didn't seem to
exist, or so it seemed from Google.

The same caller tried again, this time said his name and pressed #. I
accepted the call and from the accent it was probably a call from
either Australia or maybe South Africa. The caller wanted me to take a
survey - I will not repeat here what I said to him.
