Exchanges a public Click-to-Call token for a short-lived guest Subscriber token consumed by the Click-to-Call embed client. Use it only for a public embed flow that must place a call without exposing project credentials or requiring a full subscriber account.

Use Create Subscriber guest token when your server chooses the guest's allowed resource addresses, or Create Subscriber token for a known subscriber.
