Voice calls are not working
Diagnose problems with Rezi's AI voice agent, calls not answering, audio issues, or Retell connection errors.
Voice calling is built into Rezi: each building's number answers calls with an AI voice agent, all managed by the platform. When voice stops working, the issue is usually at the building level (the number or the voice agent is not configured for go-live) or a temporary network/quality issue. Work through these steps to identify where the break is.
Step 1: Confirm voice is enabled for the building
Open Settings > Building > Voice and confirm the AI voice agent is turned on and the building has completed go-live. A building that has not finished setup, or has voice toggled off, will not answer calls with the AI. Re-save the voice settings if you recently changed the greeting or agent instructions.
Step 2: Confirm the building's number is active
Open Settings > Building and check that the building has an active phone number. If the number shows pending or failed provisioning, calls have nowhere to land. Provisioning normally completes within a few minutes of creating the building; if it stays failed, contact Rezi support to investigate.
Step 3: Test with a direct call
Call the Rezi phone number from a different phone. If the call connects and you hear the AI voice agent greeting, the system is working. If you hear ringing with no answer, a 'number not in service' message, or silence, there is a routing or number issue, contact support. If the AI answers but audio quality is poor (choppy, echo, silent periods), this is a network-level quality issue rather than a connectivity problem.
AI voice agent not responding
If calls connect but the AI agent does not speak (silence after connection), re-save the building's voice settings to re-push the configuration, then test again. If the silence persists across multiple calls, contact Rezi support with the time of a recent test call so the issue can be traced.
Voice quality issues (echo, latency, choppy audio) are almost always network-related rather than a Rezi configuration issue. The AI voice agent uses real-time audio that is sensitive to packet loss and jitter. Test from a stable, high-bandwidth connection before concluding there is a Rezi-side issue.
Calls go to voicemail instead of the AI agent. Why?
The AI agent answers but says it cannot help with anything. What is wrong?
How do I test voice without calling from my own phone?
