This call was taken by our Google Voice answering system. There was silence for several seconds, the a woman's' voice saying Hello? then more silence and a hang-up.
I called the number back and got a recording saying: "because of a large number of calls from this number, your number has been blocked by our system. It you want it unblocked, contact us at (877) 924-7249.
I looked up the 877 number on 800notes, and reviews on this number indicate it is likely a solicitation from Birch Telecom.
This company has called us several times in the last week. He wanted us to switch our service from AT&T to Birch Communications. I told him we were on the "Do Not Call" registry, and he said it didn't matter, and continued with his spiel. I again told him about the registry, and he said, "Fine, ma'am, we do not have to lower your bill," and he hung up. Classy.
