Hi
I Don�t know the quality of Nortel equipment for VoIP, but I would not
recommend on any case, to use custom queueing if you have voice, as it
can create variable delays, and lower a lot your final voice quality.
Stay with LLC (correctly configured) on all of the path...
VoIP should get almost perfect quality, if you provide the correct
bandwidth/delay for the path
Regards!
