Caller does not speak or leave a message. Caller ID is the same as the phone number. Obviously a spoofed number. Reason for call unknown, but likely a scam artist or bill collector on a phishing expedition. Since I have a telephone with the ability to block calls. I have done so with this one and do so with any call I receive without a valid caller ID, or a message left stating its legitimate business.  

Repetitive calls from this number. No caller ID on display & no message ever left. Believed Bot generated caller. Calls occur during day & early evening. I will not answer calls with no ID as I have learned my lesson in the past.

Continuous calls from this number but no one there.

Doesn't leave a message, and calls on a daily basis.

Called while we were out ... left no message.  I called back and got a recording identifying them as the Conservative Party of Canada.
