It's Cross International which is a well know Christian aid and evengelization organization. They are telemarketing for donations to assist 3rd world countries. It's legit. If you call the number and press one, you will be removed from the calling list according to the recording.
This call comes all the time, yet when I answer it, no one says anything. I would be glad to talk to someone, but it just rings and rings and then no one answers. .
