### Answer Yes, you can set up and test webhooks without having a phone number configured. Call Event Webhooks can be registered at two levels without needing a phone number: [(1) ]() 1. Account-level webhook – Set up through the system settings' webhooks tab for events related to any agent under your account 2. Agent-level webhook – Set up through the dashboard's agent detail page (or via the

webhook_url

field on the agent) , [(2) ]() For dev work, you can: - Create your server endpoint locally [(1) ]() - Test it with sample payloads using curl/Postman before going live - Use ngrok to expose your local endpoint for testing - Verify by starting a web call in the dashboard (no phone number needed) The inbound webhook specifically is part of your phone number configuration and requires a number to be set up. [(3) ]() But the general call event webhooks (

call_started

,

call_ended

,

call_analyzed

) can be tested via web calls while you wait for your number to port. [(4) ]() , [(1) ]()
