Hi, How much attention are folks giving to network infrastructure in small environments - 6 to 12 call range? Typically, the handset switch would be used, with a PC connected. Network connections are generally 100 Mbps, existing switches are generally unmanged but managed switches are not out of the question. Network wiring quality is often unknown, but generally there aren't issues that affect data transmission. Would an investment in managed switches, Vlans, and CoS/QoS going to generally be readily noticeable in environments of this size? Thanks - Les.
