Who called from 9039651023

Called requesting to speak with person who deals with telephone service so that they could conduct a survey.  Caller did not identify who she was working for but did want to record the conversation.  I did not provide any answers.

Incoming call identified as SSI on Caller ID.  When answered, there was nobody on the other end.

Same call identified as SSI on Caller ID. Did not answer. Never do. Calls frequently around dinner time. We just blocked the call using a machine we got at Amazon.......it works.

SSI in display. Called at 4:51 PM then again at 6:38 PM. Too quick for humans so must be robo dialing. I blocked.

Got this call and the number is Denison, Tx.  Someone did say something, but it was impossible to hear what they were saying.  It also listed SSI on caller ID.
