When I set the server url for a phone number, it gives me this message: No credential is explicitly assigned to this phone number. Your organization's default server credential will be used automatically. Where are the organization's credentials?

You can find your organization's default server credentials in the organization section of the Vapi dashboard: 1. Go to [https://dashboard.vapi.ai/vapi-api](https://dashboard.vapi.ai/vapi-api) 2. Look for the Server URL and credential settings in this section. This is where organization-wide credentials are managed and will be used by default if no specific credential is assigned to a phone number. For more details, see the [Vapi documentation on setting server URLs](https://docs.vapi.ai/server-url/setting-server-urls).

I figured it out. I you have one server configuration in the Integrations, it uses that one by default, everywhere.

Hi, The

credential_id

for SIP configuration is not found in Organization Settings or Custom Credentials in the dashboard. It's generated when you create a SIP trunk credential via the Vapi API. Here's how to get your credential_id: Step 1: Create a SIP Trunk Credential via API

curl -X POST "https://api.vapi.ai/credential" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_VAPI_PRIVATE_KEY" \
  -d '{
    "provider": "byo-sip-trunk",
    "name": "Your SIP Trunk Name",
    "gateways": [{
      "ip": "your-sip-provider-domain.com",
      "inboundEnabled": false
    }],
    "outboundAuthenticationPlan": {
      "authUsername": "YOUR_SIP_USERNAME",
      "authPassword": "YOUR_SIP_PASSWORD"
    }
  }'

Replace: •

YOUR_VAPI_PRIVATE_KEY

with your API key from Organization Settings > API Keys •

your-sip-provider-domain.com

with your SIP provider's domain (e.g.,

sip.zadarma.com

,

sip.telnyx.com

) •

YOUR_SIP_USERNAME

and

YOUR_SIP_PASSWORD

with your SIP credentials Step 2: Get the Credential ID from the Response The API response will return an

id

field—**this is your credential_id**:

{
  "id": "d293b924-f68d-4cbc-850f-xxxxxxxxxxxxx",
  "provider": "byo-sip-trunk",
  "name": "Your SIP Trunk Name",
  ...
}

Step 3: Use in Your SIP URI Use that ID in the format:

{your_phone_number}@{credential_id}.sip.vapi.ai

Example:

15551234567@d293b924-f68d-4cbc-850f-xxxxxxxxxxxxx.sip.vapi.ai
