Who called from 2154862719

Called, unknown number

I don't know who this is.  Also received one right before from  267-443-6307, which comes up as Levittown, pa. like the above.

Everyday getting calls from this number (Levittown, Pa).  Last call this a.m. where person didn't
realize their voice was being recorded on my answering machine.  Some, female simpleton, probably foreigner, laughing and talking for a short time to someone on their end.

Called about 5 minutes ago, could hear someone in the background and typing noise. No one would answer, said hello 5 times, then it disconnected. I called back and it was an automated message saying the person was on the phone and to leave a message. No name no company. It came in on caller ID as Startell LLC

They called. I pick up. And no one would talk
