Consider getting a call blocking device or phone.. You can google them and many are around $40.00 or so. If its a cell phone, some already have call blocking, if not, there are free apps on the web that will work for some. You can google this. If you have a smart phone, there is a free app called call control. Iphones appear to have apps also. Another one is called Mr. Number.

Report your callers here, not just to the DNC alone:

For text messages: forwarding any text message spam you get to the short code  “7726,” which spells “spam” on most phones, to alert your network operator to the abuse. ATT won't accept 7726 But they will accept BLOCK and return a message that the web site is blocked. forward the texts to 7726 or BLOCK, depending on your phone carrier.

Call came in sounded like someone that was Asian barely able to understand wanting to talk to me regarding my insurance and my diabetes.  I informed the woman that one I could barely understand her and she was also breaking up to the point (I think she was using BVOIP or something similar)as there was alot of static breaking up and echoing.  Told her to remove my number from her list and do not call here again.  I tried to get the lady to identify the company when she called and she ignored my request.

I keep getting calls from this number and no one is there

This number keeps calling me. Nobody is on the line.

Calls a lot!  The only time I talked to someone he wanted to talk about insurance. I hung up and they keep calling.
