I use ContactAbility's direct phone transfer leads and I love the fact that they pre-screen the calls to my specifications and they spend a lot of time walking me through their real time responsive dashboard. It's an excellent lead provider that I highly recommend for volume lead buying and for running a call center life insurance operation. The best part though is the customer service, I have a great account manager that provides me with same day responses and picks up the phone when I call. I highly recommend.
