Plivo Voice API
Austin, Texas, USA
What it is
Plivo Voice API lets developers add programmable calling to web and mobile applications. Applications can make and receive calls, play audio, record conversations, and connect across PSTN, SIP, and WebRTC endpoints. Voice tools include call queues, conferences, text to speech, dual-channel recording, DTMF input, speech recognition, answering machine detection, voicemail transcription, and custom caller ID. The Audio Streams API sends raw audio from active calls over WebSocket for uses such as transcription, voice AI, analytics, and custom processing. Plivo lists integrations including Microsoft Power Automate, Zapier, n8n, Pipedream, Tray, and EngageBay, plus SDKs for Python, Node.js, Ruby, PHP, Java, .NET, and Go. Android, iOS, API, and web are listed platforms. The Voice API pay-as-you-go plan is listed at $0.01 a month; call routes and features are priced separately, with US local outbound calls at $0.0115 per minute and local inbound at $0.0055 per minute. Calls use 60-second billing increments, so a short call can be billed as a full minute. The pay-as-you-go offer includes $10 in credits without a credit card. Plivo was founded in 2011 and is headquartered in Austin, Texas.
