@John, hehehe...ati Unicast. lol! Well good to know that I can unicast you one of these days on those questions. You missed my point on the voip question because I specifically did not talk about codecs but the pipe that will carry the codecs whether G711, 723 or 729 etc.
 
But I think you have covered all that was necessary. Good one. 
 
Asante.
