Given what I experienced and what I've read elsewhere, I surmise this to be a company that does robo-calls for hire. Although, I'm not sure if they have sales reps in-house or they simply transfer the call to _their_ customer when you answer.
In any event, I received two calls, I answered the second time. CID said "TELETOWN HALL" and it was a robocall (claiming to be) from my US Congressional Rep with a "live town hall meeting" that I could stay on-line to join.
I have no reason to doubt it but still I can't completely attest to the veracity of the claim since my wireless phone glitched and hung up before I was connected.
