Uh, I've heard it claimed a lot that VOIP needs QOS.
I have not generally found that to be true.

I'd be happy to engage with you  on an appropriate networking list about
whether QOS is required.
I will agree that it is sometimes beneficial especially when links or
conjested.
However I've not found it necessary to deploy to get VOIP working on my
home network, and there are a lot of cases where it is unnecessary.

I definitely think using IPv6 (often tunneled over v4) would be a great
simplifying architectural assumption.  However I'm not aware of any
practical difference between integrated services, differentiated
services or the DSCP field between IPv4 and IPv6.  So, I'm unaware of
why v6 provides QOS advantages.
