Folks,<br><br>Excuse my ignorance ... a couple more questions on server sizing (Dell 2950)<br><br>- Hard Drive Size for open source * or *BE?<br><br>- # of Gps Ethernet ports (1 or 2? ) (I noticed one poster using one port for incoming calls and 2nd port for outgoing calls)<br>

on Sangoma's site). Using this system we are currently handling 82 users<br>quite easily. We have had at least 23 concurrent calls on a few<br>occasions with no problems. I'm pretty sure it could handle 48<br>concurrent calls as the load on this box averages around 0.11 and peaks<br>
