Ringless voicemail software places recorded messages into voicemail boxes without ringing the phone. This post is not a buyer's list and does not recommend a product. It lists what to ask a vendor, because the answers decide what you can see and control once messages are going out.

The FTC pages summarized below describe how prerecorded messages and their opt-outs are treated, which is what several of the questions turn on.

Why software is the last question, not the first

Software determines how a message is sent. The rules attach to who sends it, what it says and who receives it. A tool that sends perfectly still carries whatever the campaign says and to whom.

The FTC's Telemarketing Sales Rule guide says the rule covers outbound calls that deliver a prerecorded message, including messages left on an answering machine or voicemail service. The table restates this and the neighboring points.
