To enable your Vozzo AI Agent to participate in PSTN telephony (traditional phone calls), you can assign a dedicated phone number to it. Vozzo manages the underlying SIP and telephony infrastructure using Plivo.
Assign a Phone Number
To attach a purchased phone number to your voice AI agent, use the /agent/deploy-phone/{agent_uuid} endpoint. When anyone calls this number, your agent will answer using its configured prompt, voice, and knowledge base.
