About NexaVoxa
NexaVoxa is a web platform for building and running AI voice agents that handle business phone calls, including answering calls, qualifying callers, booking appointments, and passing calls to a person. Users name an agent, define its behavior through a single prompt or a step-by-step guided flow, attach knowledge sources such as pages, documents, and recordings, and set the tools and data fields the agent uses during a call. Agents can be tested from the browser before they are connected to a phone line.
Agents connect to phone numbers through Twilio, Telnyx, or a SIP trunk, and each number can be routed to a specific agent. Outbound campaigns can place calls from a contact list, with numbers validated before dialing. Each call is recorded, transcribed by speaker, and logged with its summary, sentiment, duration, outcome, and cost, and analytics cover volume, latency, success rate, and spend. The homepage describes the product as built for teams handling high call volumes. Pricing is not stated on the homepage.
