Who called from 6105430000

Received two calls from this number in the same day.  First call had the number for the caller ID.  Second call had VERIZON.  I answered the second call.  The caller identified his company as Eastern Research.  He was taking a survey on opinions of the presidential candidates and local state candidates.

they called twice in the past 3 hours, both times nothing...nut i could hear them breathing in the background!!!

been getting calls from this number off and on all evening. When answered nothing is said. Call number back and it is not a working number.

I do not answer the call, but they keep calling back and leaving no message.  Received two calls today and two calls yesterday.  Annoying!!

Multiple calls from this number-all showing as Verizon. Called back and got nothing but a busy signal.
