How can an unknown phone number show as an outgoing call from my landline?

This morning we had about 15 spam calls in a period of an hour. In looking at the phone log on my account it shows an unknown phone number listed as the outgoing number. We made no outgoing calls while all of these spam calls were made. The outgoing calls lasted for a minute or longer.

How can this be?? I did go in and block all of the suspicious numbers.

    Hi @dkr102030 , welcome to our community!

    It's very unusual that you received these calls but the call log is showing them as outgoing. Are these calls showing as billable calls with a charge next to them? What do they show for call type?

    I would suspect Caller ID spoofing,

    My recommendation would be to go into Spectrum's Voice Zone Settings to review your Caller Privacy Settings. Additionally, check that both Call Guard Settings are activated.

    Activate Nomorobo, It still works with Spectrum Voice, and will drop calls after the first ring so that they can't leave a message on your machine. You will see the number on Caller ID on TV if you have Spectrum Cable TV with a Spectrum box, but the caller can't leave a message, I have combined the use of Spectrum Call Guard with Nomorobo. It works great! Here is how to activate Nomorobo:

    Finally, report problematic callers that Call Guard is missing here:
