I am setting up a VOIP system on a trial basis for a small business with less than 10 employees. Each has a computer and will now also have a digital phone (connected over 10/100). Their needs are pretty standard. They use their data connection for regular internet use and for a VPN connection to another branch (though that data requirements for it are very lean. it's actually a text-based program they use over the vpn). We're looking at no more than 5-6 concurrent data phone calls at a time.
My question is, how much do I need to spend here? I'm looking at the L2 Netgear FS726T (http://www.newegg.com/Product/Product.aspx?Item=N82E16833122146&Tpk=FS726T
) and it seems to be everything I need. Should I spring for a L3 switch or would that be overkill?
