In their own words
Plum DEV
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.
Wazo Platform
Wazo Platform is a free, open-source stack of telecom microservices for building programmable voice, video, messaging, and presence services. Its capabilities include audio and video calls, chat, call centers, conferences, voicemail, custom call routing, and an auto attendant. Interfaces include WebRTC, REST APIs, WebSockets, and Webhooks, described as mobile- and web-friendly. The microservices are developed in Python, and APIs are described through OpenAPI specifications. Asterisk, RTPEngine, and Kamailio make up the telecom engine; RabbitMQ, NGINX, and PostgreSQL support the technical core. Wazo can be deployed on bare metal, virtual machines, or containers. The documented all-in-one installation uses Debian 12 Bookworm and Ansible; minimums for a small production installation of about 50 users are 2 CPUs, 4 GiB RAM, and 50 GiB storage. The GPL-3 license allows free use, including commercial use. APIs can integrate billing and services such as speech-to-text, AI, or sentiment analysis. Community support is available through Mattermost, a forum, and JIRA.
