Hi I'm sending the bot to call but it takes 20/30+ seconds to actually ring.
What can we do to make it faster?

Twillio outbound is immediate.

from api call finished successfully to envoke this single call, to actually phone ringing, 30seconds~

Hello <@562019149040320552> , can you share a screenshot of the API response that shows the timestamp ?

{
insertId: "698512610007978a6cc8863f"
labels: {4}
receiveTimestamp: "2026-02-05T21:57:53.502061664Z"
resource: {2}
severity: "INFO"
spanId: "1260990798350623434"
textPayload: "VoiceAgentAPI: created batch call successfully, batch_call_id: batch_call_e60b4af1bc36f3e36ebfc"
timestamp: "2026-02-05T21:57:53.497546Z"
}

will doing POST /create-call endpoint directly fix this problem?

Yes if you used  /create-call  it will run immediately .
