Do you need to Vlan and segregate the voice traffic and apply QoS to ports on Cisco Catalyst Express 500 Series Switches?  Just discovered that these devices has no CLI.  Presently the site has 100+ IP phones on a flat network with no issues.  Any advise is appreciated.

You don't need to do anything if everything is working well. What is your weakest (slowest) link on the network? There is where you want QOS if VoIP is traversing that link.

Some would argue that you need QOS on the LAN but I don't get it. Never had a LAN VoIP issue, it is always a WAN issue.
