I get calls several times a day. Same deal as others have posted: 3-rings, hangs up, no message. I did a little research and believe this is Americas Health Brokers (AHB) Sales. They're nationwide, but as brokers operate by state, residents in CA get calls from the 925#. I had recently done a little internet inquiry into health insurance and the new legislation, so the timing makes sense. I've just blocked them.
I get three calls a day - to my CELL PHONE, which is on the Do not call list...3 rings then hangs up. One at 8am (ish) one at noon(ish) then one at 5(ish). I am just blocking them.
