Spec score 7.1 #15 of 20 in Interactive Voice Response Software

What it is

Plum DEV is a cloud developer platform for automating processes through voice and building interactive customer self-service applications. Its VoiceXML foundation lets developers control customer interactions, including inbound IVR and inbound or outbound SMS. SMS requires an SMS-ready phone number. APIs connect DEV with CRM, ERP, voice-of-customer, telephony and other database systems, and it also works with Plum Fuse. Developers can customize branding, call flows and backend database integrations. Multiple text-to-speech and automatic speech-recognition engines are supported, including Amazon Polly, with dozens of languages and dialects. Integrated VoiceTrends tracks usage and performance, supports script A/B testing and provides granular reports. Plum says DEV runs on custom telephony data centers and AWS, with on-demand scalability and a 99.9% uptime SLA. It describes the platform as PCI-DSS Level 1 and HIPAA compliant, while customers remain responsible for configuring applications for applicable requirements. Pricing is available on request. Demo accounts have limited access and no call logging.
