Who called from 9040000000

It is 12:42 A.M....just received a cell phone call from 1-904-000-0000.
Of course, did not answer it.
Does anyone know who or where this call is from?

Thank you.

advises they are ict service by an automated voice.  Request a passcode to be entered.

I got a call last night in the wee hours. Around 1am. I don't recall answering it because I was asleep. But this is ridiculous.

calls me 3 to 4 times a night around 1am to 4am

A few months ago this number dialed into my cell phone. i called it back and i guess it directed my to 911 dispatch either it really did direct me to dispatch or he is a very good impersonator if you get an more info. please help
