Certainly! To receive call cost information through webhooks, you'll need to ensure that your webhook is configured to receive billing-related events or transactional information from your telephony provider. Typically, call cost data is sent as part of a Call Detail Record (CDR) after the call has ended.
Here's what you can do:
1. Check your telephony provider's documentation to understand how they send billing information.
2. Ensure that your webhook endpoint is set up to receive and process the specific event or message that includes call cost data.
3. If your provider supports it, you may need to subscribe or enable billing events explicitly in your provider's dashboard or via their API.
If you've already done this and still can't receive call cost information, it might be an issue with the provider's service or a misconfiguration on your end. In that case, contacting your provider's support would be the best course of action.
If you need further assistance with the configuration on the VAPI side or have any other questions, please let me know!
