As the conversation designer, you can preview a conversation without having to register to it by going to the "start" URL:
https://app.voicevoice.com/start/[URL keyword]
Where [URL keyword] is the unique identifier of the conversation. You can view the URL Keyword of a conversation in the Conversation Settings dialog.
Note: the "start" url is not publicly visible and is intended for designers to preview a conversation. Normally participants attend a conversation by first registering to it and then joining at the scheduled time.
