I've a customer with a 2600G, 2.5.9 firmware

They have a home office with a couple of cordless VOIP phones (one base station, therefore one IP address - 192.168.235.15)

They also have a Sony TV with built in BBC iPlayer, Five OD etc

What's the best way to set up QOS so that the VOIP is getting priority?
*********************

Second, related, question is almost the reverse - in the evening, when watching iPlayer, due to their rural location and 1.4mbs broadband, any downloading etc from laptops affects the speed of iPlayer so ideally iPlayer/The TV would have priority.

OK, question one has been answered now - the VOIP handsets used standard SIP port 5060.
