White-label AI voice agents purpose-built for verticals like property management, IT support and real estate.

What it does

Callin.io provides white-label, industry-specific AI voice agents that businesses and agencies deploy under their own brand. Built on its low-latency Neuron engine, agents answer calls, triage issues and execute workflows for verticals such as property management, IT support, real estate and smart cities.

How to use: Sign up for the free trial or book a demo. Upload your website, documents, and FAQs so the agent builds its knowledge base, then choose the voice and set transfer rules, hours, and priorities. Connect a new number, port your existing one, or link your PBX via SIP trunk, and integrate calendars and CRMs (Google Calendar, Outlook, HubSpot, WhatsApp, or custom systems via API and MCP).
