Received phone call from number fairly late at night.  Second time in one week. No message left.

When you call this number it reaches a service that contacts people on the behalf of various "charitable organizations" ~ when I listened to the list of organizations there are a bunch of "Associations of the Deaf" from different states, Salvation Army, Enlisted National Guard Associations, and so on.   Sort of a clearinghouse for all of these orgs that obviously pay for the service.   There is an option to get on the Do Not Call list from any of the member organizations, not sure if it works for the number itself.  

Serves many "partner charities":
charities/non-profits
direct mail services
paging services
helping sick and missing children
helping people in armed services

So essentially a telemarketer serving non-profits?

Received multiple calls, I did not answer, no message was left.

Answered phone--no one there.

Call from this number again.  Is there a place to report these calls to the police or something?

Keep getting this call.  No message.

Received phone call late in evening. No message left.
