If you attempt to call BT's domestic help service and answer truthfully that have a 2Wire 2700HGV modem (i.e. the BT Business hub) they will immediately redirect you to the BT Business help service.
When you arrive there, BT Business help cannot help you at all as they are only able to look at BT business lines so you do not exist in their eyes.
However I've had no difficulty with other ISPs who will usually listen to your reported performance figures, even though no other ISP is allowed to support the 2700 as it is a closed bespoke BT product.
I have found the 2700 to be an ideal and cheap test tool and much more sensitive than BT's JDSU test equipment which seems to have been de-tuned to a lower performance.
Thank goodness for all the help available here though !
