Voximplant

Voximplant is a voice AI orchestration platform and CPaaS for building voice agents and other communication services, from AI receptionists and appointment reminders to contact centers, cloud PBX and in-app calling. It runs on a proprietary telephony network that carries 5 billion calls a year, so teams can focus on building voice agents while Voximplant handles scaling and reliability. At its core, Voximplant is serverless. You sign up, buy a phone number and upload your call logic in JavaScript to the Voximplant cloud. There, the code runs automatically whenever a call comes in, whether from the phone network, a SIP device, or the Web and Mobile SDKs. It can also be triggered by an HTTP API request. There's no backend to host or scale. Developers write the logic themselves, while PMs and founders can build with their AI coding agent and Voximplant Agent Skills. A basic voice agent can be set up in about 15 minutes without telecom experience. Because AI orchestration runs on the same platform as the call rather than on top of a third-party telephony provider, latency stays low and the agent has direct control over the call. That includes built-in turn detection, voicemail detection (AMD), transfers, recording and barge-in, as well as HD audio. For the AI side, Voximplant connects natively to OpenAI, Gemini, ElevenLabs, Deepgram, Cartesia, Ultravox, Inworld, xAI Grok and Dialogflow, with 315+ TTS, ASR and LLM combinations, and you can bring your own LLM and API keys instead. To help teams get to production, Voximplant lets you debug live calls with breakpoints and review full session logs in call history. Once you go live, phone numbers are available in 100+ countries, along with SIP trunking, WebRTC and WhatsApp Business, served from 15 global data centers. Infrastructure starts at $0.004/min, with AI usage billed by the provider. Whether you're automating missed-call recovery, qualifying leads the moment they come in or running a full contact center, Voximplant gives you the telephony and the AI orchestration in one place. The platform is GDPR and HIPAA compliant and ISO 27001 certified, and it is trusted by companies like 8x8, Skyro, Plata and ID Finance.

ZEGOCLOUD

Our journey in audio and video hardware and software development started back in 2001. The core team focused on key technologies in digital signals, algorithms for voice and video, as well as network transmission. We’ve learned from years of experience that delivering real-time audio and video is no easy feat. It can only be achieved with a wealth of knowledge in many different fields. Yet in this digital era, there are so many use cases for voice and video interaction to build bridges and forge links. So we started to explore how to share our passion for and expertise in audio and video solutions with more businesses and developers as a partner in their journey of success. That’s why we founded ZEGOCLOUD in 2015. With Real-Time Communication (RTC) empowered by AI, ZEGOCLOUD now seeks to turn the vision for Real-Time Interaction (RTI) into a reality. We lay the groundwork for businesses and developers to build RTI into their apps across mobile internet and the metaverse. Flexible, customizable, low code.
