What it is

Plum Fuse is a visual, low-code flow builder for production-grade IVR applications, available through web and API with cloud deployment. It targets CX leaders and non-technical teams without VoiceXML expertise, while producing full VoiceXML 2.1 output. More than 37 production-ready templates and NLU-powered conversational AI are included. API connections can link CRM, billing, scheduling, and internal systems in real time. Integrations include Google Dialogflow, Amazon DynamoDB, and Amazon S3, with S3 used only for call recordings. PCI-compliant DTMF masking keeps payment card digits out of agent views and call recordings. The Fuse API handles outbound and bulk call queues, status, cancellation, and call-log retrieval. Recorded audio remains temporarily in memory and is deleted when calls end; it is not stored. Session logs remain for one rolling year, while detailed call logs remain five days. Plum Voice states that it holds PCI DSS Level 1, SOC 2 Type II, Cyber Essentials, and ISO 27001 certifications, with a 99.9% uptime SLA. Pricing is on request.
