Hi, short term listener first time caller.....

Bit odd, got a call earlier (13.59) as i was fixing lunch (week off work!*), silence on the other end. Hung up and tried to 1471 for all the good i thought it would do... as my cordless was dialling the number there came a string of other DTMF tones that caused the system to give me a 'cannot reach this number' error. Whizzed over to the base station and pulled the cord for a half minute to be sure nothing else dodgy was going to happen and then tried again. Surprisingly, it actually gave me a number.

0870 428 0216

Unfortunately I haven't been able to find any leads on this after a fair bit of web searching, the only hits i've had are for other people trying to figure it out also. Naturally all attempts to find cost-free reverse phone directories have drawn a blank except for here and the SayNo database doesn't list it either.

Anyone have a clue as to who these particular clowns are?

Going to give my provider's (Virgin...**) customer service number now, as it was congested earlier and i didn't fancy pratting about with the phone whilst trying to finish making and then eating my food. See if they can shed any light or tell me if any other outgoing attempts have been made at that time or any other time.

* Concerning thing is this might have been happening at various other times whilst we've been out. Don't know if there's any way they can trigger the phone line to do a callback without it actually being picked up, but it trying to dial numbers by itself is a bit of a worry.
** Yeah, think I'll get anywhere?
