Who called from 2030063103

I have received calls from this number 203-006-3103 3 X's in the last week and they just hang up when the phone is answered or they do not leave a message. I am a cell user in Arizona and have no clue who this would be.

caller with an unusual number came through around 10pm and answered they just hung up after few seconds. Not too sure why or who as did not recognise the dialling code.

Called on my O2 mobile from 02030063103 at 15:19 today

Did not answer call, no idea of what it is.

Weird I got a missed call from that number today too. Listed as 0002030063103 on my Orange mobile. Doesn't connect when ringing back.

Had a chat with a guy trying to sell me freecalls from a landline, he hung up as soon as I told him I got free calls already from Taktalk. Scam
