What Plum DEV is
Plum DEV is a developer platform for building voice-based customer self-service applications and automating processes. Its VoiceXML foundation lets developers control interactions and create inbound IVR applications, while APIs also support outbound calls, SMS, and call logs. SMS requires an SMS-ready phone number; because texting is unencrypted, it cannot use PCI phone numbers or infrastructure. DEV connects through APIs with CRM, ERP, telephony, voice-of-customer, and database systems, and also works with Plum Fuse. Developers can select from multiple speech recognition and text-to-speech engines, including Amazon Polly, with dozens of languages and dialects. Integrated VoiceTrends tracks usage and performance, supports script A/B tests, and provides granular reporting. Plum says the service runs on custom telephony data centers and AWS under a 99.9% uptime SLA. It describes the platform as PCI-DSS Level 1 and HIPAA compliant, but customers must configure their own applications for applicable requirements. Pricing is available on request.
