I'm new to networking and need help with design/config. We have two internet providers (T-1 for 35 VoIP phone and FIOS for everything else). Currently our networks are separated by two routers and everything is working fine. I want to use a dual WAN router primarily for it's fail-over feature since our business is critically dependent on a working internet connection. I would like to know what would be the best network design for us to use dual-wan fail over router and two switches (one switch for voip phones and the other for everything else). I want to keep traffic separated where voip phones are solely using T1. Also would be a good idea to create 2 VLANs (for voip and data).
Dual WAN router: Cisco RV042G
Netgear GS748TP ProSafe 48-port 10/100/1000 Smart PoE Switch for VoIP
Netgear ProSafe 48-Port Gigabit Smart Switch (GS748TNA) for data
Any idea would be greatly appreciated.
