I was just looking for some advice as to where to find the best information such as websites on VoIP. I head researched hosted VoIP a couple of years ago and at that time, I thought I had learned I would need a switch compatible with VoIP (I bought a PoE one), some type of "brain" (maybe a VoIP gateway), plus the phones or seats. I also thought I would require quite a bit of bandwidth such as at least 512Mbs or more. And that was part of the reason for the QOS. The rough cost estimate for 7 $200 VoIP phones, the "brain" (sorry, I can't remember the term), and the switch was going to run around $7000 plus the monthly cost for each seat from the host.
I am still looking at this as I still have regular PBX, but we are also talking about it on an Electronic Medical Record message board. Someone there is stating he has VoIP with Cisco phones that only require 16kbs. Yes, 16kbs. I told him I didn't think that would be possible. Then, combine that with some of the suggestions about Skype and Vonage, and I don't think everyone is understanding the differences.
So, can anyone suggest what sites to go to and how much bandwidth should be used?
