Hello, Vapi Support. Right now, all the Assistant is doing is holding for about 2 minutes and then ends the call. But we need it to hold for at least 1 hour before dropping the call. Let me know if you need additional information

To increase the assistant's hold duration to 1 hour, set the

maxDurationSeconds

property to

3600

in your transfer assistant configuration. Here’s an example:

json
"transferPlan": {
  "mode": "warm-transfer-experimental",
  "transferAssistant": {
    "firstMessage": "Hello, I have a customer on the line. Are you available to take this call?",
    "maxDurationSeconds": 3600
  }
}

This will keep the customer on hold for up to 1 hour before the call is dropped. Note: This works with Twilio, Vapi numbers, and SIP trunks only. For more details, see the [assistant-based warm transfer documentation](https://docs.vapi.ai/calls/assistant-based-warm-transfer). Source: - [Assistant-based warm transfer documentation](https://docs.vapi.ai/calls/assistant-based-warm-transfer)

This looks like a JSON snippet. Where exactly do I put this? The only place in my build that involves JSON is in my webhook from GHL that triggers the call in Vapi. So do I put it there?

Hi, The 2-minute drop is because Vapi defaults

maxDurationSeconds

to 120 seconds on the transfer assistant. You just need to bump it to 3600 (1 hour). If you set up your assistant in the Vapi dashboard: Go to your assistant → find the

transferCall

tool → inside the destination config, find

transferPlan

→

transferAssistant

and set

maxDurationSeconds

to

3600

. If your GHL webhook sends the assistant config to Vapi: Yes, the change goes in the JSON payload. Find the

transferCall

tool in your structure and add the field here:

{
  "type": "transferCall",
  "destinations": [
    {
      "type": "number",
      "number": "+1234567890",
      "transferPlan": {
        "mode": "warm-transfer-experimental",
        "transferAssistant": {
          "firstMessage": "Hello, I have a customer on the line. Are you available?",
          "maxDurationSeconds": 3600
        }
      }
    }
  ]
}

The key field is

destinations[].transferPlan.transferAssistant.maxDurationSeconds

. Best, Vapi Support

This worked! Thank you!

no worries!
