In a nutshell my small family business has comcast as a isp and a 3d party voip provider. Comcast as a business grade isp is not good in my neck of the woods (Chicago). My research ( google) informed me that I could use a Sonicwall tz215 and a 2nd isp as a fallback in case (ie: when) comcast craps out. can I use the fully configured Cisco router (static ip's for the phones and computers and VoIP stuff ) in line from the Sonicwall. So what I'm thinking is isp/isp-->Sonicwall -->Cisco router -->dumb switch?? Can this be done --if so how?
