Agent Voice Response vs Avaya Experience Platform

Agent Voice Response is a self-hosted system that turns an Asterisk PBX into a real-time voice AI agent. Callers can interrupt while it speaks through voice-activity detection. Its composable microservices let operators swap automatic speech recognition, language-model, and text-to-speech engines. It supports Asterisk AudioSocket on Asterisk 18 and later, including named systems such as FreePBX, VitalPBX, Vicidial, Elastix, and custom dialplans. Listed integrations include OpenAI, Anthropic, Deepgram, ElevenLabs, Google, Ollama, Vosk, Kokoro, Ultravox, OpenRouter, CoquiTTS, and Silero. Noise cancellation and echo suppression are described before audio reaches the model. Local deployments can use Vosk or Silero, Ollama, and CoquiTTS or Kokoro, keeping caller audio on the network according to the maker. Docker microservices can scale horizontally behind a load balancer. AVR is free for personal and commercial use, with no license keys or per-minute charge. Setup requires Docker images, provider configuration, and an Asterisk dialplan extension.

Avaya Experience Platform, also called Avaya Infinity, coordinates omnichannel customer interactions with enterprise systems, data, AI and workflows. It supports inbound calling, outbound dialing, IVR building, digital channels and workforce management for large, complex contact centers, including environments with thousands of agents. Teams can create low-code or no-code workflows, while authorized business users can update them under IT governance. Avaya describes the orchestration as AI-agnostic and supports multiple models, real-time customer context and automated workflows. Deployment choices include cloud, hybrid and on-premises, with API, self-hosted and web platforms. Listed controls include role-based access, audit trails, retention settings, bring-your-own-key and organization-defined permissions. Integrations include Salesforce, Microsoft Dynamics 365, ServiceNow, Zendesk, Microsoft Teams and Verint. Digital costs $48 a month, Voice 83.00 USD, and All Media 125.00 USD, based on 200–399 concurrent users over three years; additional charges may apply.
