A seasonal, interactive voice agent that answers phone calls 24/7 with the personality of Santa Claus. It is trained to answer children's questions, tell holiday stories, and spread Christmas cheer, creating a magical brand experience.
Retailers, shopping centres and family brands compete hard for attention in December, and most Christmas campaigns look alike: a catalogue, a discount and a Santa photo booth with long queues. A 'Call Santa' phone line is a memorable alternative that families can use from home at any hour. Staffing one with human actors is impractical, though. It needs many simultaneous lines, consistent character performance, evening and weekend coverage, and careful handling of conversations with young children.
An AI Santa voice agent answers calls with a warm, consistent Santa character, chats about wish lists and reindeer, tells short festive stories and ends with a brand-appropriate sign-off. Because the callers are mostly children, this is a campaign where safety design matters more than cleverness. The script must stay tightly in character, avoid collecting personal details, steer away from sensitive topics, and handle difficult moments, such as a child mentioning a sick parent, with a gentle, pre-written response and a suggestion to talk to a grown-up.
A phone number is provisioned through a voice platform such as Vapi, connected to a telephony provider, with an opening message telling parents the call is with an AI character.
Speech-to-text transcribes what the caller says in real time, and a language model generates Santa's reply from a tightly written character prompt and approved story library.
A safety layer checks each reply before it is spoken, blocking promises about specific gifts, requests for addresses or surnames, and any off-topic or inappropriate content.
A warm, festive text-to-speech voice speaks the reply, keeping latency low enough that young children do not talk over Santa or lose interest.
Calls end after a set time with a friendly goodbye. Only anonymised call metrics are kept, and flagged conversations are reviewed by the campaign team for script improvements.
A retail brand launches a 'Call Santa' hotline during the holidays. The Vapi-powered AI agent handles thousands of simultaneous calls, creating a memorable experience for families and generating significant positive PR and brand loyalty.

Calls from children involve personal information under the Privacy Act 1988, so the safest design collects as little as possible: no names beyond first names spoken in conversation, no addresses, and no retained recordings unless you have a clear purpose and parental consent. Recording and listening devices laws differ between states, so disclose at the start of the call if audio is recorded or transcribed. The eSafety Commissioner has published guidance on child safety online that is worth reviewing. Avoid marketing directly to children through the call, and make sure any follow-up offers go to parents with consent that meets the Spam Act 2003.
This solution requires careful evaluation of cost-benefit ratio. Consider implementation only after thorough analysis and risk assessment.
It can be made reasonably safe with careful design: an upfront disclosure for parents, a tightly restricted character prompt, a content filter on every reply, no collection of personal details and prepared responses for sensitive topics. Nothing is foolproof, so run supervised testing, monitor launch week closely and give parents a way to report concerns.
Around two to four weeks, which means planning should start well before December. Time goes into writing and approving the script, choosing a voice, setting up the phone number, building safety filters and testing with families. Leave buffer for legal review and load testing before promoting the number publicly.
It should not. Promising gifts creates problems for parents, so the character is instructed to listen warmly to wish lists without making commitments. Santa can mention being busy in the workshop and encourage kindness, but should never name specific products, prices or store offers to children on the call.
