Who called me from his number? They have called a few times but never left a message. It's an Oregon number but who?
+1 (971) 334-8213

I have no idea who they are either but I know they've called me multiple times the last 2 weeks and they have multiple phone numbers that are the same all except the last 2 digits. I have had 8213, 8234,8223 as the last 4 digits call my phone. No message is ever left.

Same story as the others who commented.   Several calls a week from similar numbers.   No message is ever left.  I have blocked all of them.
971-334-8213,  971-334-8292, 971-334-8307

They have called me twice today, I called the first number back (8292) and it sounded maybe like a debt collector? They called again from 8213, again no message was left.

I got a call from 971-334-8207...the guy said he represents Comcast, but i thought 971 numbers were cell phone numbers...I didn't give him any info cause it does not sounds like a regular Comcast number
