Hi, I would like to offer to you a good Firewall able to handle Traffic Q.O.S also good switch running on a specific VLAN to split voice traffic from common traffic; are you using certificated cabling also? Do you still have cascade switch? All of these things seems to be very simple but when you are talking about voice over the network, the latency time, routes and etc can contribute for good or bad experience! Let´s talk.
