According to their support guy (who sound very knowledgable), since

QOS is not all that useful. It only works in the router for outgoing
packets, and if you are sending lots of big packets upstream, e.g.
filesharing, then you are going to have problems anyway. Latency is
the killer of VoIP and it goes up quickly if your send connection is
saturated.
If you do use P2P throttle your total upload to about 1/30th bytes per
second of your speed in bits per second, e.g. a 256k connection should
be no more than 10k bytes per second, and may need to be less, try 7.5
or 5 if you get too much jitter.
Having no dialer as it were, means you are using MPLS, which some
people have problems with. If it does cause problems, then it will be
pretty obvious. People have complianed on this list that HOT only
guarentees port 80 (HTTP), but I think they have since gotten better
about it.
If you have a router, are you sure it's not doing tunneling (the
equivalent of a dialer) already? If it is using DHCP then you really
are using MPLS and do not have any tunneling, if you are using an
L2TP, PPTP, PPoE, etc connection you are.
This is only based on what they told me, I will know more tomorrow,
and if
there is something to update, I will.
Update the list either way please. Someone will ask the same question
again in a few months and at least they can find a response if they
search the archives.
Thanks, Geoff.
