Can any of the Ringcentral approved routers support a Comcast and AT&T input?

My companies primary internet provider is Comcast. We've been having on and off again issues with them recently so we had AT&T install a backup line for internet connectivity. Can any of the Ringcentral approved routers support two internet connection inputs and switch between them if it senses issues with the primary connection? I would like to avoid having to physically pull out the network cable and switch it in case I'm not at the office.
