I am developing an Oauth2 Webhook application. I have added several phone.x events to my webhook subscription, however the only ones which appear to fire are phone.callee_call_log_completed and caller_call_log_completed.
As an example, I have subscribed to all phone.warm_transfer related events, however when initiating / completing a warm transfer, I receive not warm_transfer events in my webhook.
This is all via the development event notification endpoint, using ngrok.
