Since going independent, I no longer have the use of my former BD’s Do Not Call filter.  Normally, this isn’t an issue, since I either ask for permission @ the initial contact, or develop clients from referrals.

  However, occasionally it doesn't work that way, but I'd still like to contact them.   Does anyone know any reliable sources for screening these numbers?  I checked the government site, but it's built to discourage this type of activity.
