by any chance is there a standalone vm app that will work with RW?
In terms of a standalone app that works with Republic’s voicemail, I’m afraid not.
It’s possible to use Republic’s voicemail forwarding to send voicemail to another service that would have its own app. Google Voice is the most commonly suggested option.
YouMail is another possibility. Historically, the free version of YouMail has not worked with Republic, however, based on another member’s experience that seems to have changed: How to forward Samsung voicemails to a visual voicemail app.
