Thinking in Public
Call center jobs are likely gone.
If you have experience in a call center, that is where I would start. Build a farm of bots making calls. Probably debt collection.
You know what the scripts say, which objections come up and what the compliance rules are. A bot needs all three. Collection calls are regulated, and the bot has to follow the same rules a person does.
The people who know the room are the ones who should build the machine that replaces it.
In the United States, the Federal Communications Commission ruled in February 2024 that the Telephone Consumer Protection Act covers AI-generated voices. A call that uses an AI voice counts as an artificial voice call, and it needs the prior express consent of the person called, unless an emergency or an exemption applies. Rules differ by country, so check the ones where your calls land.
I think the first job is to write down what you know. Put the scripts, the common objections and the compliance rules in one document, in the order a call goes. A bot gets its instructions from that document, and a person with call center experience can write it better than anyone. Then test it. Play the hardest caller you remember and see where the script breaks.
