I have a data lan on a 192.168.x.x network and a voice lan on a 172.20.x.x I would like to be on my data network and communicate with my voice network interface. I researched and came up with a default route? if so do I put a static route on both data and voice routers or just the data router? or do I need another command to make this work. Also I will not bog down my network when this happens? my friend mentioned setting a qos command? all help appreciated!
