AI Outbound Caller: questions to ask

From The AI Agents Report by Iterategy · iterategy.com/research/ai-agents/jobs/ai-outbound-caller/

The nine questions

Does an AI do this, or does a rule? If the answer is “when X happens it sends Y”, you are buying automation, and it should not cost AI prices.
Does it send, or does it draft? Ask for the sentence on their page that says it acts on its own.
Does it do it on its own on this plan, or on the one above? The setting that lets it act without you is often a tier up from the entry price.
What does it do with the hard cases? Ask what it holds back for you, and what happens to what it cannot resolve.
What is the cap, and what happens past it? Work out the bill at the volume you actually do, not at the included allowance.
What is the unit? Per month, per user, per location, per minute, per credit or per resolved ticket.
Who does the setup, and is it in the price?
What happens to the changes it made when I stop paying? Some tools make changes that stay only while you subscribe.
Who carries the legal side? For calling and texting customers, ask who handles consent and opt-outs.

Several of these are platforms, not products: you get a builder and a phone number, and someone still has to write the agent, load the list, connect the calendar and register the numbers.
The rate on the page is rarely what you pay. Published examples add a monthly fee or a monthly minimum on top of the per-minute rate, and the rate goes up once included minutes run out.
You are responsible for the consent rules on calling, and help with them is often on a higher plan. Ask what the vendor handles and what is left to you.
Your number can get flagged as spam, and some vendors sell protection against that separately.
9 of the 19 can be bought with a sign-up form, and several let you start on a per-minute rate today.
