I really liked the nbx itself but couldn't stand 3com and when they made everyone go through the certification process for the second time i dropped them. Never even sold a system since i was so scared and unsure of 3com and their support. Funny part is they cold called me a month or two ago to see if i had any interest in being an nbx dealer - apparently they don't know i was a dealer or remember the pompous arrogant manner that they displayed in our dealings. As for VOIP itself yesterday i made a call from a remote ip phone in an outbuilding 1000' away from the ksu and connected via wireless access points. It then connected via an ip link over the internet to another site in another state, grabbed dial tone from that remote site and made a local phone call. For a period of time it was even crystal clear!! Kind of an interesting application and to have it all come together and work was a fun thing to see.
