Set everything up and it all works like a dream, However my wireless router does not have QOS, However I can give priority to a device via it's ip address and the ports it uses however what 'ports' do Voipfone use! (Port Forwarding)
I am not having any problems and my sound quality is just fine at present but I have not been using my broadband that heavily and should I start then I may get problems when using the phone at the same time so hence the reason why I'm asking this question now!
I have found over on the Vonage UK forum people are using the following ports in order to setup their router, below is a copy of the thread:
Are these the ports my PAP2 will use to transmit my data/calls through?We set our Draytek to prioritise UDP ports 10,000 to 20,000 and it works like a dream.
I also read the following which askes the same thing really but never seemed to get an answer so I hold out little hope of any answer myself: http://www.voipfoneuserforum.com/viewtopic.php?t=354
