### Answer I noticed you're experiencing calls that end unexpectedly right after the first assistant message. This issue could be related to a few reasons covered in the troubleshooting guides. One common reason might be the assistant recognizing an "end call phrase" inadvertently embedded in the conversation or setup, which is known to prematurely end calls as detailed in the Discord discussion where it was highlighted that calls can end if the first message or setup contains phrases meant to end calls under certain conditions [(1)]() . If this doesn't seem to be the case for your scenario, it might be beneficial to review the assistant's configuration and ensure there are no unintended phrases or setup that could trigger such behavior. Additionally, checking for any updates or changes in your configuration around the time this issue started occurring could offer some clues. Given the unique setup of each Vapi assistant and call flow, without access to the specific configuration and logs, it's challenging to provide a pinpoint diagnosis. If the issue persists and doesn't seem to align with known scenarios, considering reaching out directly to Vapi support with your call ID and details might be the next best step for a detailed investigation.

or add it if you don't have it in the api
