I am getting the same calls and are very annoying.  Today I have counted and it is up to 25 and no one is on the other line.  Just for your information, I am on the gov. do not call list and I'm still getting these calls.  I did report it today to them.  Hopefully this will do something.  Last week I was bothered by a 703-436-2020 &703-436-2019. Same thing, a recording asking for someone's name who is not in my household saying if this person is there press 1 and we have a very important message.  Hope this helps.

I usually get calls from this number on random days.  However, on those days I will receive anywhere from 10-15 calls. Picked up once and no one answered.This has been going on for most of this summer.

Another annoying recording about a credit card we do not own! We have been bombarded with these calls and suspect that they all come from the same call center or company, despite different information showing on the called ID each time.
When all or mostly zeros show up, we suspect they are using a device to block being traced. "Illinois" indicates they are probably using cell phones

This number has called my house  5 times today.  They don't leave  a mesage and when I pick up they don't say a thing.  Very annoying!

This number shows up on my caller ID 8 times yesterday. Never a message; sure it's some kind of auto-call as the time associated with each call ends similarly: i.e., 4:04 p.m.; 5:04 p.m.; 5:54 p.m.; 6:44 p.m., etc.  Really, is this necessary?! Geez, can't wait to see how many times it tries us today.
