Cold calling AI means one of three things: an AI caller that dials prospects and talks in an AI voice, a live assistant that helps a human rep during the call, or an AI prospect that reps practice cold calls on. AI callers can work a list without a rep on the phone, but in the US a call that uses an AI-generated voice falls under the TCPA's artificial-voice rules (FCC, February 2024), so it generally needs the called person's prior express consent when it goes to a cell phone or a home line. Live help and practice keep a person on the call. Della offers all three: the Della AI Caller, Della Live and Della Practice.

The 3 kinds of cold calling AI

AI that makes the calls

An AI cold caller (some people say "AI cold calling bot") works from a list and a script. You upload contacts, tell it what to say and what it should know, and set the days, hours and budget. It dials, talks in an AI voice, answers questions and common objections from your playbook, and books a meeting or flags a warm lead for a rep to call back.

Where it can help: more calls made than your reps have hours for, the same answer every time, and every call recorded and reviewable. Where it struggles: some prospects hang up when they hear an AI, and long, high-value or relationship sales usually need a person. In our view the best use is a short, clear ask, with a rep taking over the moment someone is interested.

The rules: AI voices are robocalls under the TCPA

Not legal advice. These are the main US rules to know before an AI voice calls anyone; talk to a lawyer about your own lists.

• AI-generated voices count as "artificial" voices. In February 2024 the FCC confirmed that the Telephone Consumer Protection Act's limits on artificial or prerecorded voice calls cover AI technologies that generate human voices (FCC Declaratory Ruling 24-17, February 2024).
• Consent first for cell phones and home lines. The TCPA bars artificial-voice calls to cell phones and residential lines without the called person's prior express consent, with narrow exceptions. Telemarketing calls of this kind need prior express written consent under the FCC's rules.
• "B2B" lists still contain cell phones. Many business contacts list a mobile number. The rule follows the type of line called, so check consent for those numbers too.
• Do-not-call. Honor the National Do Not Call Registry where it applies and keep your own do-not-call list. Stop calling anyone who asks.
• Recording consent. Some states require everyone on a call to agree to recording. State telemarketing laws can add their own rules on top of federal ones.

What the Della AI Caller does: Della says she's an AI and that the call is recorded on every call. If someone asks to stop, she ends the call and adds the number to your do-not-call list. Consumer lists need a consent checkbox before Della will dial them. She calls only on the days and hours you set, and stops at the weekly budget and hourly limit you choose. You stay responsible for following calling laws where you call.

AI that helps your reps on cold calls

Here a person makes the call and the AI stays silent. It listens, and when the prospect says "send me an email" or "we already have someone," your team's best answer appears on the rep's screen while the prospect is still talking. After the call, it scores what happened. Because your rep is the one talking, this isn't an AI-voice call, but the normal cold-calling rules still apply: do-not-call lists, calling hours, and recording consent in states that require it.

This is what Della Live does. If reps already get conversations and lose them at the pushback, this is usually the bigger lever; our guide to improving cold-call conversion with AI explains why, and cold call objection handling tools covers that one job in detail.

AI that helps reps practice cold calls

An AI prospect picks up, raises real objections out loud, and grades the rep when they hang up. Reps can warm up before a call block or drill the objection they folded on yesterday, without pulling a manager off the floor. See how to practice cold calling by yourself and a 10-minute cold-call warm-up.

Which should you use?

• You have a large list of people who agreed to be called, and a simple ask (book a time, confirm interest): an AI caller can work through it, with reps taking the warm leads.
• Your reps get conversations but book few meetings: live assist on their real calls, plus practice on the objections they miss.
• You're hiring or ramping new reps: practice first, then live assist on their first real calls.
• You're not sure your lists have the consent an AI voice needs: keep a person on the call and use live assist and practice until you've checked.

Many teams use more than one. Della runs all three from one dashboard, with one script and knowledge base behind them.
