As soon as I answer the phone there is a long wait time. Once the Agent starts speaking the wait times very short which is good. Makes for a good conversation. Its just the beginning of the call that has a long wait. How can I fix this?

Lower waitSeconds in startSpeakingPlan like to 0.2, disable smartEndpointing, minimize silenceTimeoutSeconds, responseDelaySeconds, and llmRequestDelaySeconds, and use faster LLMs like GPT-4.1 Nano and TTS models..

@Kings_big💫 Thanks for your advice, unfortunately this hasn't improved it. The wait times during the conversation aren't long at all they are pretty natural actually, its just the beginning of the call that is a long wait

Try reduce onNoPunctuationSeconds to 0.5sec, enable smartEndpointing, set waitSeconds to 0.8sec, and ensure minimal logic or payloads in the first message to fix it..

Thanks @Kings_big💫 . What I ended up doing was telling it to speak a message in the beginning instead of waiting the person on the otherside to say something.

Use firstMessage with firstMessageMode: "assistant-speaks-first" so the agent starts the call with a greeting, avoiding the initial wait for user input..
