Great service, and I'm enjoying a good chunk of those 70,000 calls you block every day. The only improvement I can recommend is some way to mute the single ring that you're unable to stop. Guests sometimes ask why our phone rings only once, which does give us the opportunity to explain your service. Keep up the good work.

I wish it would not ring once when a robo call comes in. Can't the call be completely blocked instead?

Blocks at least several junk calls every day!
