@Vapi @Vapi Support Bot I’m working on call flows in Vapi and want the agent to greet differently depending on whether the call is outbound or inbound. I tried using the

call.type

variable, but it doesn’t seem to distinguish properly between inbound and outbound calls. Here’s the snippet I’m using: {% if call.type == "outboundPhoneCall" %} - "Hi {{firstName}}, this is Lexi with NEXA Mortgage. We helped with your last FHA or VA home loan, and I'm reaching out as part of your quarterly mortgage review. I hope you're having a great day." {% elsif call.type == "inboundPhoneCall" %} - "Hi {{firstName}}, this is Lexi with NEXA Mortgage. Thanks for calling! You’ve been invited to learn more about our Quarterly Mortgage Review." {% endif %} How can I correctly distinguish between inbound and outbound calls in Vapi so the greeting script triggers appropriately?

Hi, The variable

{{call.type}}

is not available in Vapi’s template system, so it cannot be used directly in system prompts or first messages. Recommended solution: Pass a custom variable using

assistantOverrides.variableValues

, then reference it in your prompt. For outbound calls (via API):

POST /call/phone
{
  "assistantId": "your-assistant-id",
  "assistantOverrides": {
    "variableValues": {
      "callDirection": "outbound",
      "firstName": "John"
    }
  },
  "phoneNumberId": "...",
  "customer": { "number": "+1234567890" }
}

For inbound calls (via the assistant-request webhook):

{
  "assistantId": "your-assistant-id",
  "assistantOverrides": {
    "variableValues": {
      "callDirection": "inbound",
      "firstName": "Jane"
    }
  }
}

You can then reference this variable in your prompt to control the first message logic. Alternative: Use separate assistants for inbound and outbound calls, each with its own first message. Best regards, Oshi Raghav Customer Support Vapi
