Who called from 8183672550

Just got a call from some guy with a thick accent who claimed to be from Southwest Airlines inviting me as a "VIP Guest" to some grand opening they're doing in Bloomington, MN. I told him I wasn't interested and hungup.

Gal calling from Southwest inviting me to grand opening in Bloomington, MN.  One she started probing for personal information, I hung up.  Sounded like a scam.

Have receive two calls - Porter Erma.  No message left.
Called the number back - it just rings and rings.
If they call again, I will block.

Got a call from this phone no. they did not leave a message. Just left their phone on, sounded like they were having a party. It was recording on my answering machine for at a least 5 minutes. No one  
ever responded. Sounds like someone was just goofing off or drunk.

Received a phone call. heard some faint background voices but silence after a few seconds then silence.
