We will be implementing a Shoretel VoIP system and video conferencing system across 3 locations. Location 1 has approx 50 users, Location 2 and 3 have approx 20 users each. Limited growth expected beyond that at each location.
We have Cisco 1841 Routers connected to a MPLS network providing QOS for voice, video and data. We are now looking for a switch infrastructure internally. We are considering layer 2 Dell POE switches due to the attractive price but are also considering setting up a separate VLAN for our voice traffic. If we were to do that would we need a layer 3 switch at each location?
