Legit phone calls being blocked. How do I let them through?
Enthusiast - Level 1

I occasionally get calls from a research company I am signed up for. The caller ID is legit, but the calls get blocked after one ring. I then get a call from a town and state ID with a different number, but is the same company, so I still get the call. But why is it blocking the legit number and how do I change this to allow it to come through?
