Agent Voice Response vs Voicent

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.

Voicent develops software for automated voice, email, and text communication, with point-and-click controls for sharing information and exchanging ideas. Its hosted service runs in a browser and can be accessed from computers, phones, and tablets. Cloud plans include call-center features such as agent dashboards, predictive dialing, and campaigns. Cloud calling covers the USA and Canada; on-premise software supports worldwide use with local phone and text services and requires Windows. Voicent says its cloud service has no contact limit and allows unlimited contact imports without extra fees. Calls are billed from pickup to hang-up, with a 30-second minimum followed by six-second increments. Features include call recording, voicemail drop, and dialing modes such as predictive, progressive, preview, click-to-call, and alternate phone dialing. CRM integrations include Salesforce, SugarCRM, Zoho CRM, MySQL, and Voicent CRM. The service lists a free plan, paid options from $19/mo, and a 30-day trial. Standard support is available weekdays from 8am to 5pm PST, excluding holidays or closures.
