AI phone agent: an AI call center that answers and makes calls

An AI phone agent is an AI voice agent that holds real phone conversations: it answers inbound calls and places outbound calls, understands what the caller needs, takes action in your tools and follows up on WhatsApp or email. Run many of them together and you have an AI call center for support, sales, appointment booking and collections. With Jelliu you launch one without code. Start on the Free plan (15 voice minutes every month, no credit card); paid plans start at $79/month.
