Vapi ends call autmatically, want to display custom message

Have your assistant speak the message, then call the endCall tool or add the message to endCallPhrases in your assistant settings so it ends the call after saying it..

i want to give message in between the call, for example are you there?, Is there someting I can help you with? before the call gets silence time out

Use idleMessages in the messagePlan with idleTimeoutSeconds set to trigger prompts during silence..
