When webhooks are triggered

• Incoming calls: When a call arrives on a service configured with a webhook URL. Services using static SVAML behavior (STATIC) do not trigger this webhook.
• Call events: When the service is configured with a webhook URL and the SVAML command does not have an events property defined. If the events property is present — even if empty — no webhook is triggered for that command's events. For example, a dial command with no events property will trigger a webhook when the call is answered; a dial command with events: {} will not.
• Custom events: When a webhook SVAML command is executed explicitly during a call.
