Plum DEV
What it is
Plum DEV is a cloud developer platform for automating processes through voice and building interactive customer self-service applications. Built on VoiceXML, it lets developers control customer interactions and create inbound IVR use cases. It also supports inbound and outbound SMS, which requires an SMS-ready phone number. APIs can connect the platform with CRM, ERP, voice-of-customer, telephony, and other database systems, and DEV also works with Plum Fuse. Developers can customize branding, call flows, and backend database integrations. Speech options include multiple text-to-speech and 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 on-demand scalability and a 99.9% uptime SLA. Pricing is available on request. Plum describes the platform as PCI-DSS Level 1 and HIPAA compliant, while making customers responsible for configuring applications to meet applicable requirements. SMS is unencrypted and incompatible with PCI phone numbers and infrastructure; demo accounts have limited access and no call logging.
