I have a workflow in GHL with a webhook setup to connect to Vapi. After a few tests, the webhook failed to execute and gave me this error: Custom Webhook Action error: Custom Webhook Action error: {"message":"Couldn't Start Call. Numbers Bought On Vapi Have A Daily Outbound Call Limit. Import Your Own Twilio Numbers To Scale Without Limits.","error":"Bad Request","statusCode":400} Please let me know what other details I may need to provide.

To bypass Vapi's 10 daily outbound call limit, import your own Twilio number: 1. Purchase a number through Twilio (if you don't already have one) 2. Get your Twilio credentials - Account SID & Auth Token from Twilio's "API keys & tokens" section 3. **Import via Vapi dashboard**: - Go to "Phone Numbers" section → click "Import" - Enter your phone number, Account SID, and Auth Token - Click "Import" Your imported Twilio number will now have unlimited outbound calls.

Vapi numbers come with a daily limit on outbound calls, which has led to the error you're encountering. To overcome this limit, you can import your own Twilio numbers, which don't have the same restrictions. This will let you scale your outbound calls without limits. If you need guidance on how to import numbers, let me know, and I can provide more details.

hey, sorry to piggyback here. just wanted to confirm. if i bring my own SIP trunk (and a number from a provider like Viva Telecalling), will i still encounter this error? or will this error only come for the free Vapi numbers and this SIP trunk number will continue working as expected?

If you bring your own SIP trunk (e.g., with a number from Viva Telecalling), you will not encounter the daily outbound call limit error—this restriction only applies to free Vapi numbers. To scale without limits, set up your SIP trunk in Vapi as shown below:

bash
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",
    "gateways": [{"ip": "YOUR_SIP_PROVIDER_DOMAIN", "inboundEnabled": false}]
  }'

For the free Vapi number limit, the documentation does not specify if it is per number or per organization. Source: - [Vapi SIP Trunk Documentation](https://docs.vapi.ai/advanced/sip/sip-trunk)

i understand. thank you. but how can we get more clarity on if the limit is per number or per organisation? we're facing this in production and we're servicing the healthcare industry. if we could get more clarity here, it would allow us to service our doctors and patients better.
