Plivo

Plivo is a cloud communications platform that now centers on building and running voice AI agents. It combines a no code agent builder with carrier grade telephony, so teams can deploy phone agents that answer or place calls, look up records, book appointments and send follow up messages. Developers can build in two ways. The programmable route offers SIP trunking and bidirectional audio streaming with noise cancellation, with guides for connecting LiveKit and Pipecat agents to real phone numbers, and SDKs for Python, Node, Go and REST. The studio route lets a user describe an agent in a prompt and have it created. The platform also carries SMS, WhatsApp, chat and a Verify API on its Enterprise plan. The vendor cites latency under 500 milliseconds, coverage in more than 150 countries, and compliance options including BAA, HIPAA and SSO. It suits developers building conversational voice products and businesses that need inbound support, outbound feedback or scheduling calls handled by an agent. Pricing is pay as you go with no lock in, and new accounts get $10 in free credits with no credit card required. A Voice AI Agent costs $0.03 per minute excluding telephony. SIP trunking and audio streaming calls start at $0.0010 per minute outbound and $0.0028 per minute inbound. The pay as you go tier covers the United States and India. Enterprise starts at $1,000 per month and adds coverage across 190 plus countries, with SMS from $0.0077 per message and WhatsApp messages from $0.0034.
