What Plum DEV is

Plum DEV is a cloud developer platform for automating processes through voice and building interactive customer self-service applications. It uses VoiceXML to control customer interactions and supports inbound IVR, as well as inbound and outbound SMS. SMS requires an SMS-ready phone number. Developers can customize voice applications, including branding, call flows, and backend database integrations. APIs connect DEV with CRM, ERP, voice-of-customer, telephony, and other database systems; it also works with Plum Fuse. The platform supports multiple text-to-speech and speech-recognition engines, including Amazon Polly, and dozens of languages and dialects. Integrated VoiceTrends tracks application usage and performance, supports script A/B testing, and provides granular reporting. Plum says DEV runs on custom telephony data centers and AWS, with an SLA guaranteeing 99.9% uptime. It describes the platform as PCI-DSS Level 1 and HIPAA compliant, while customers remain responsible for configuring applications to meet applicable requirements. SMS is unencrypted and incompatible with PCI phone numbers and infrastructure. Pricing is on request.
