Who called from 8184643752

Got a call from this number. I have downloaded an app called 'truecaller', said the company name is Logipos from Van Nuys, CA. Seems if you search within this site, the name 'Logipos' pops up register to a different number.

got a call from 818-464-3752 , leaves no messages. i dont answer numbers that i dont know and if it was really important i think they woulda left a message on my voicemail. i dont know who the caller is so they go to my reject list.

another sales call promising something to do with energy efficiency.

Keep getting calls from this number and other numbers that are similar. When I call back, I get a "this number is not in service message!"

The cid showed "voip caller" and phone number 818-464-3752.  Left no message.  Blocked.

Rejects.
