Hi,<br><br>Age old question it seems but I haven't been able to get a
handle on it yet. Let's assume I'm using a g729
codec. If I wanted to handle 20 simultaneous calls, how much
bandwidth would I need? Is there a general formula for this?<br><br>I tried this caluclator:<br><a href="http://www.voip-calculator.com/calculator/eipb/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">

wasn't sure what "Packet Duration to select so I took the default 20ms
(2 samples) - whatever that means. I plugged in 5 for the BHT (20
customers, each getting 3 X 5 minute calls/hour = 5 Erlangs) and the
default 0.01 for the Blocking. It worked out to 264 kbps.
Does this sound reasonable? If so great! A business DSL
could support this.<br>

Comments welcome!<br>
