Thought this was worth a post.

Appears that some ISP's (offering Call packages) can not prevent your private number from being listed. (seems TPG is the main culprit)

I dont know the full details (sorry) but I would think that if you have bothered to have a silent number, and recently taken up another ISP deal (as we all know) all of them are pushing hard for a slice of the pie.

Only to find your number listed, it would be of some concern.

Perhaps a quick check on to make sure your not one of them
