I have a customer with a very simple network, 2 WAN connections going into a Sonicwall TZ-210, then one switch on a 192.168.1.0 network with single CAT5e drops on each office. They are using RingCentral phones/ service. I would like to segment the VoIP from the LAN and basically have the phones go out to the world from the X2 WAN which is bunch of T1 and everything else will go out from X1 - fiber connection.
How would I go about achieving this? If I get a good HP switch that can do a layer 2-3 VLANs, will that solve my problem in being limited by office drops? Any ideas/ documentation on this?
