According to their support guy (who sound very knowledgable), since I have HOT infrastructure, no dialer, and a router, they simply connect their box to *my* router, as an additional client. This means that no port blocking,

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.
