Who called from 8186960403

They just called and left voicemail but didn't say anything?

Since October 2016, this number has called me and never left a message.
Can only conclude there's nothing important about their call.
This "Location: California (Agoura Hills, Burbank, Calabasas)" is wrong.
The true location is out of Glendale, California.

Calls daily and leaves no message. Damned Armos checking to see if they have a valid # to use in some fraudulent scam, no doubt.

Just called left vm with no sound just a beep. blocked
