Answered with hello and then beeping. Blocked

Both wife and I received calls from this number. We did not answer. I called back and sounded like busy tone.

I just got a call from this number on my cell phone. I did not answer since I did not recognize. Now a blocked number.

Same issue , call then nobody on the other side .
