Asterisk to OpenAI Realtime PRO
The Problem: Slow and Rigid Phone Interactions
In today's quick business world, calls often lag or feel robotic: old IVRs don't understand natural speech, force long waits for a human, or fail to resolve any query, frustrating customers and slowing your team. For example, high latency causes delayed responses in support calls, leading to customer drop-offs; rigid menus ignore context, leaving basic questions unanswered. Without proper tools, these talks feel disconnected, hurting trust and efficiency.
InfinitoCloud's Community Edition for integrating Asterisk with OpenAI Realtime fixes these basics with low-latency interactions, smooth voice activity detection (VAD), and custom prompts that can specify multi-language support, making it much more useful for users worldwide. For advanced needs like full audits and agent transfers, the PRO steps in, restoring calm, enhancing satisfaction, and reducing churn by up to 30%.
