Who called from 4086185111

As soon as I picked up the phone after two rings they disconnected.

just got a call on my cell from this company and a dead line.

I've received several calls from this number over the last few weeks. They don't leave a message and I don't pick up because I don't recognize the number. Who are they?

I received a call from this number. Not knowing who this call was from in the South San Francisco Bay Area. I answered it on speaker,but on mute. Waiting for them to speak, a woman's voice stating she was Gail said hello then hung up ? She did not say what they were soliciting or purpose ?

I'm pretty sure this is a robo dialer.
