Good morning, Since yesterday, we have been experiencing an issue with voice traffic during calls. At intervals, the agent goes silent and does not speak. After analyzing the logs in VAPI, we observed that the voice agent stops responding because the audio is transmitted through an ElevenLabs WebSocket on channel 8. When a new WebSocket (channel 9) is opened, the system, due to its internal routing logic, assumes the audio will be transmitted via channel 9. Once channel 8 closes, the audio stops playing, and as a result of this bug, the agent remains silent. I am sharing the Call ID: 019c8f0b-0733-7aa4-ab8c-c23866e7c5f5, along with the corresponding capture showing the exact moment when the incident occurs. We look forward to your review and guidance to help resolve this issue. Thank you in advance for your support. Best regards, Sergio https://cdn.discordapp.com/attachments/1475801907569365057/1475801907736870954/Vapi_error.jpg?ex=699ecf21&is=699d7da1&hm=68a1ae75e1d48d6b317d0623e13703c22b7cace08ddafedd2c68f5f781ca127e&

To quickly diagnose the agent silence issue, please: 1. Go to your [Vapi dashboard](https://dashboard.vapi.ai/). 2. Navigate to

Observe > Call Logs

, locate the Call ID

019c8f0b-0733-7aa4-ab8c-c23866e7c5f5

, and review the tool execution and error sections for any anomalies when the silence occurs. This will help pinpoint where the audio routing or tool execution failed, and you can share these findings with support for faster resolution. For more details, see the [debugging guide](https://docs.vapi.ai/debugging). Source: - [Vapi Debugging Documentation](https://docs.vapi.ai/debugging)
