Is this a technical support scammer?

Windows Tech Support Scam is the thread that they found on here.

The post is fairly old, with the first number having really nothing to it and it just rings forever, and the second going to a Radius Solutions LLC in Oregon with numlookup saying their caller ID is DSOFT. However calling the second number leads me to tech support, but they want a customer ID and won’t tell me who they are. The third number, your 5066 number, answers as Resonate Solutions, but rings indefinitely.
