I have implemented VOIP several times. Anyone that syas the quality is not as good doesn't know what their talking about. The quality is just as good, PROVIDED that you have dedicated bandwidth via dedicated lines or QoS set up for it. NEC maks a very nice switch (don't remember the exact name) that will do POTS and VOIP at no extra charge. Every switch maker has VOIP solutions.

Second, you may have to have the infrustructor in place (CAT5) that is seperate from your usual network wiring. It's not a stretch that by now you may not even need seperate CAT5 network medium for it as this technology is advancing very quickly.

I also use VOIP at home (Vonage if you need to know) and I have set up QoS for it. It works so well that I have abandon my POTS line and it saves me $110 a month. When my TelCo (Verizon) learned that I was truning off my POTS they asked if I was moving. I said "Yes, I'm moving to VOIP", the rep actually got mad. That was 6 months ago. Competative might be one word. But when you consider that there are no taxes local or federal for VOIP and there isn't going to be any effective way to tax it, it's a POTS killer for the TelCo's. I pay NO long distance PERIOD and I can talk my head off 24x7.

Bottom line, VOIP is the direction everything is going and I'm sold.
