9490752-2372 shows on called ID as CTI and there is never anyone on the line and they never leave a message. They've been calling me for weeks. My number is supposed to be on the Do Not Call List.
Very annoying, who are they?

They keep calling and then hanging up.  At least twice a week.  Not sure if I should hit redial as it is a long distance number.  How can i get them to stop?

CTI is a minority owned collection agency ...if they are calling you, they are trying to collect a debt of some kind...can always answer the call and dispute their claim, but in their mind, you owe somebody something ...they have bought the debt.

I've been receiving several calls from this number for the past few days. I never pick up the phone on numbers I don't recognize. It says "800 Service" in my caller ID. Does anybody know which company this is?

I have had calls from this number and several others.  Caller ID identifies it as CTI ... whatever that is.  There is never anyone on the other end.

gotten several calls from this # don't know who it is
