With uni-v the phone runs separate to the internet. Also it's possible to have separate providers, eg: phone with Telstra and internet with Optus.
What a load of BS. uni-v IS VOIP! The main differences are that UNI-V ONLY uses G711 codecs and is always marked TC-1 priority. ALL packets are still routed to the RSP (that is from both UNI-V & UNI-D ports). A UNI-D VOIP service using G711 with TC-1 priority marking is EXACTLY the same as a UNI-D service as far as the NBN is concerned. The UNI-V service uses EXACTLY the same internet as the UNI-D service - if the internet goes down, so does your phone.

UNI-V is no different to any other service as far as supplier goes. In fact a lot of lower cost ISPs do not provide a voice service at all and encourage you to go to a third party like MyNetFone if you want one.
