Does anyone know of a way to prioritize traffic on a BYOB VoIP solution, or does it even matter?

QoS on BYOB is handled at the router. Some VoIP providers have HCL (hardware compatibility lists) that recommend certain routers that support QoS within their configuration schemes. Also, your if you have a hosted VoIP provider, they will recommend certain Carriers or Network Providers that are preferred to operate their VoIP infrastructure over and that they can pseudo manage. When it comes to hardware, check with your VoIP or Carrier provider first…then look at other alternatives like Edgemark, Cisco and Adtran.
