With this, you might have answered your own question. Whatever the technical capabilities or bling of the box itself, they are a nightmare of a company to deal with. Having cancelled my telephone/broadband service with them in October 2012 they continue to send me letters with an ever increasing bill that they allege I owe to them, claiming that I actually requested to retain these services. So far they have failed to produce evidence of the request and respond to my email enquiries with something so obscure it must have been randomly generated by an automatic translator. They also have no viable complaints procedure.
You have been warned.
