I stayed on the line to speak to a person and acted like something just came up. The person identified himself as Patrick and said I could contact him again at the number listed from the caller ID (which may be faked/false). Since I have all my telephone numbers currently active in the national do-not-call list, I have reported the violation. The FTC can subpoena my incoming call record from the telephone company and get the correct origin number if the caller ID was spoofed. The call was just after 8:00 PM.
Call received at 7:28pm. I did not answer because I did not recognize the area code and no caller ID was listed (only the number). No message was left.
Call received at 7:43 p.m. Unknown name with above #. Did not answer.
