About

VoiceOI is a web-based platform for building and running outbound voice bots for call centers, BPOs, lead-generation teams and other outbound operations. Users create recorded-voice bots with branching scripts or conversational AI agents in a visual builder, test call flows in a simulator, and run campaigns through VICIdial or a SIP carrier. Bots can qualify leads, detect answering machines, respond to spoken do-not-call requests and transfer qualified callers to human agents. The platform supports bulk provisioning and outcome write-back in VICIdial, campaign management, call records and transcripts, optional AI-voice disclosure, and Google Sheets exports on eligible plans. Pricing is prepaid per concurrent bot, with carrier charges billed separately. VoiceOI is designed for outbound calling; bot features, telephony options and workflows vary by plan.
