They don't leave voicemails. If you do answer, there seem to be two possible outcomes. One is that they ask for someone by name without saying why, and won't say anything other than the name of the person they're calling for until they hang up. But they'll keep calling. Sometimes, when you answer, you instead get a pre-recorded message that says: "Hello. Donor Services Group is trying to reach you on behalf of a non-profit organization you support. Unfortunately, we cannot connect the call at this time. We apologize for the inconvenience. If you have any questions, feel free to call us at 661-476-3044. Thank you." Seems to be this company, but they have no obvious way to be added to their "Do Not Call" list online:
