Dear Vapi Support Team,
I am experiencing a persistent "Silence Timed Out" error on my inbound Vapi Assistant, and the call hangs up immediately upon connecting. I have followed all the troubleshooting steps, and the issue appears to be an internal configuration glitch on your end.
We need to resolve this tonight to get the system operational.
Account and Assistant Details
Vapi Assistant ID: ReefTek Journal Follow-Up Agent
Twilio Phone Number: +1 xxx=xxx-xxxx
Error Code in Vapi Logs: Silence Timed Out (repeatedly)
Recent Call ID Example: (.)
Troubleshooting Performed (Confirms Connectivity)
Twilio Webhooks Verified: Confirmed the Twilio Voice Webhook is correctly set to
https://api.vapi.ai/twilio/inbound_call with an HTTP POST method.
Vapi Connectivity Confirmed: The call successfully hits the Vapi system and generates a log entry, but the agent fails to speak immediately.
Model Speed Ruled Out: Switching the LLM from GPT-4o Mini Cluster to the full GPT-4o Cluster did not resolve the timeout.
Assistant Logic Verified: The System Prompt includes a direct, explicit command for the agent to speak immediately upon connection.
Funding Confirmed: Account has a positive credit balance ($9.48).
Latency Adjustment: The waitSeconds parameter was adjusted in the Speech Configuration.
Request:
Please investigate the backend logs for the provided Call ID and manually reset the configuration between my Twilio number and the Assistant ID. This appears to be a known internal issue that requires your direct intervention.
Thank you for your urgent attention to this matter.
Sincerely,
Rick
