On Incoming calls the caller hears nothing but silence on their end, but my ring profiles and frequency are defaults. Persists through reboot.
The ringing tone that a caller to you hears is not generated by your OBi.
Perhaps if you give some relevant details you might get some concrete advice.
I am not sure what info you need but I am using VoIP.ms and set up according to their documentation. If you can let me know what info you would like I can likely get it.
