Currently our network is all in one subnet and all the switches are setup in their default un-managed mode. We are using 2 Dell Power Connect 2724, 2 Dell Power Connect 3448p and an Untangle 8.1 running the firewall/router.
We have AAstra 6757i phones and are constantly having issues with the phones going out. I believe it's most likely due to nothing being configured and the phones are getting too much broadcast traffic.
Right now every location has several ports so if chosen to do so every pc and phone can have it's own port to the switch, or we can daisy chain the PC through the phone and the phone connects to the wall. What is going to be the best practice for reconfiguring the network for better performance and will these switches suffice?
Should we configure VLANS for data and voice and have every station and phone use it's own port or daisy chain the PC through the phone? What about using the 3448p for just the phones in their own VLAN and the 2724 for the rest of the devices also in another VLAN?
